How to Write a Bibliography, With Examples

You spent the past six hours grinding out your latest paper, but finally, it’s finished. It’s late, you’re exhausted, and all you want to do is click “Submit Assignment” and then get some sleep. 

Not so fast. If your paper doesn’t have a properly formatted bibliography, it’s not finished. 

A bibliography is a list of all the sources you consulted while writing your paper. Every book, article, and even video you used to gather information for your paper needs to be cited in your bibliography so your instructor (and any others reading your work) can trace the facts, statistics, and insights back to their original sources.

What is the purpose of a bibliography? 

A bibliography is the list of sources a work’s author used to create the work. It accompanies just about every type of academic writing , like essays , research papers , and reports . You might also find a brief, less formal bibliography at the end of a journalistic piece, presentation, or video when the author feels it’s necessary to cite their sources . In nearly all academic instances, a bibliography is required. Not including a bibliography (or including an incomplete, incorrect, or falsified bibliography) can be considered an act of plagiarism , which can lead to a failing grade, being dropped from your course or program, and even being suspended or expelled from your school. 

A bibliography accomplishes a few things. These include:

• Showing your instructor that you conducted the necessary research for your assignment 
• Crediting your sources’ authors for the research they conducted
• Making it easy for anybody who reads your work to find the sources you used and conduct their own research on the same or a similar topic

Additionally, future historians consulting your writing can use your bibliography to identify primary and secondary sources in your research field. Documenting the course information from its original source through later academic works can help researchers understand how that information has been cited and interpreted over time. It can also help them review the information in the face of competing—and possibly contradictory or revisionary—data. 

In nearly all cases, a bibliography is found at the end of a book or paper. 

What are the different kinds of bibliographies?

Different types of academic works call for different types of bibliographies. For example, your computer science professor might require you to submit an annotated bibliography along with your paper because this type of bibliography explains the why behind each source you chose to consult.

Analytical bibliography

An analytical bibliography documents a work’s journey from manuscript to published book or article. This type of bibliography includes the physical characteristics of each cited source, like each work’s number of pages, type of binding used, and illustrations. 

Annotated bibliography

An annotated bibliography is a bibliography that includes annotations, which are short notes explaining why the author chose each of the sources. Generally a few sentences long, these notes might summarize or reflect on the source. 

An annotated bibliography is not the same as a literature review . While a literature review discusses how you conducted your research and how your work fits into the overall body of established research in your field, an annotated bibliography simply explains how each source you used is relevant to your work. 

Enumerative bibliography

An enumerative bibliography is the most basic type of bibliography. It’s a list of sources used to conduct research, often ordered according to specific characteristics, like alphabetically by authors’ last names or grouped according to topic or language. 

Specific types of enumerative bibliographies used for research works include:

National bibliography

A national bibliography groups sources published in a specific region or nation. In many cases, these bibliographies also group works according to the time period during which they were published. 

Personal bibliography

A personal bibliography lists multiple works by the same individual author or group of authors. Often, personal bibliographies include works that would be difficult to find elsewhere, like unpublished works. 

Corporate bibliography

In a corporate bibliography, the sources are grouped according to their relation to a specific organization. The sources can be about an organization, published by that organization, or owned by that organization. 

Subject bibliography

Subject bibliographies group works according to the subjects they cover. Generally, these bibliographies list primary and secondary sources, whereas other types of enumerative bibliographies, like personal bibliographies, might not. 

Other types of bibliographies

In some cases, it makes sense to use a bibliography format other than those listed here. These include:

Single-author bibliography

This type of bibliography lists works by a single author. With certain assignments, like an essay comparing two of an author’s books, your bibliography is a single-author bibliography by default. In this case, you can choose how to order the sources, such as by publication date or alphabetically by title. 

Selected bibliography

A selected bibliography is a bibliography that only lists some of the sources you consulted. Usually, these are the most important sources for your work. You might write a selected bibliography if you consulted a variety of minor sources that you didn’t end up citing directly in your work. A selected bibliography may also be an annotated bibliography. 

How is a bibliography structured? 

Although each style guide has its own formatting rules for bibliographies, all bibliographies follow a similar structure. Key points to keep in mind when you’re structuring a bibliography include:

• Every bibliography page has a header. Format this header according to the style guide you’re using.
• Every bibliography has a title, such as “Works Cited,” “References,” or simply “Bibliography.”
• Bibliographies are lists. List your sources alphabetically according to their authors’ last names or their titles—whichever is applicable according to the style guide you’re using. The exception is a single-author bibliography or one that groups sources according to a shared characteristic. 
• Bibliographies are double-spaced.
• Bibliographies should be in legible fonts, typically the same font as the papers they accompany.

As noted above, different kinds of assignments require different kinds of bibliographies. For example, you might write an analytical bibliography for your art history paper because this type of bibliography gives you space to discuss how the construction methods used for your sources inform their content and vice-versa. If you aren’t sure which kind of bibliography to write, ask your instructor. 

How do you write a bibliography?

The term “bibliography” is a catch-all for any list of sources cited at the end of an academic work. Certain style guides use different terminology to refer to bibliographies. For example, MLA format refers to a paper’s bibliography as its Works Cited page. APA refers to it as the References page. No matter which style guide you’re using, the process for writing a bibliography is generally the same. The primary difference between the different style guides is how the bibliography is formatted. 

The first step in writing a bibliography is organizing all the relevant information about the sources you used in your research. Relevant information about a source can vary according to the type of media it is, the type of bibliography you’re writing, and your style guide. Determine which information you need to include about each source by consulting the style guide you’re using. If you aren’t sure what to include, or if you’re not sure which style guide to use, ask your instructor. 

The next step is to format your sources according to the style guide you’re using. MLA , APA , and the Chicago Manual of Style are three of the most commonly used style guides in academic writing. 

MLA Works Cited page

In MLA format , the bibliography is known as the Works Cited page. MLA is typically used for writing in the humanities, like English and History. Because of this, it includes guidelines for citing sources like plays, videos , and works of visual art —sources you’d find yourself consulting for these courses, but probably not in your science and business courses.

In MLA format, books are cited like this:

If the cited book was published prior to 1900, is from a publisher with offices in multiple countries, or is from a publisher that is largely unknown in the US, include the book’s city of publication. Otherwise, this can be left out. 

Scholarly articles are cited in this format: 

• Author(s). “Title of Article.” Title of Periodical, Day Month Year, pages.

APA References page

In APA format —the format typically used in psychology, nursing, business, and the social sciences—the bibliography page is titled References. This format includes citation instructions for technical papers and data-heavy research, the types of sources you’re likely to consult for academic writing in these fields. 

In APA format, books are cited like this:

Digital object identifier (DOI).

(issue  number) , article’s page range (i.e., 10-15). URL.

Chicago Manual of Style

The Chicago Manual of Style (CMoS) permits authors to format bibliographies in two different ways: the notes and bibliography system and the author-date system. The former is generally used in the humanities, whereas the latter is usually used in the sciences and social sciences. 

Both systems include guidelines for citations on a paper’s body pages as well as a bibliographic list that follows the paper. This list is titled Bibliography.

In CMoS, books are cited like this:

publication.

number  (year published): page numbers of the article (i.e., 10-15).

What is Bibliography?: Meaning, Types, and Importance

A bibliography is a fundamental component of academic research and writing that serves as a comprehensive list of sources consulted and referenced in a particular work. It plays a crucial role in validating the credibility and reliability of the information presented by providing readers with the necessary information to locate and explore the cited sources. A well-constructed bibliography not only demonstrates the depth and breadth of research undertaken but also acknowledges the intellectual contributions of others, ensuring transparency and promoting the integrity of scholarly work. By including a bibliography, writers enable readers to delve further into the subject matter, engage in critical analysis, and build upon existing knowledge.

1.1 What is a Bibliography?

A bibliography is a compilation of sources that have been utilized in the process of researching and writing a piece of work. It serves as a comprehensive list of references, providing information about the various sources consulted, such as books, articles, websites, and other materials. The purpose of a bibliography is twofold: to give credit to the original authors or creators of the sources used and to allow readers to locate and access those sources for further study or verification. A well-crafted bibliography includes essential details about each source, including the author’s name, the title of the work, publication date, and publication information. By having a bibliography, writers demonstrate the extent of their research, provide a foundation for their arguments, and enhance the credibility and reliability of their work.

1.2 Types of Bibliography.

The bibliography is a multifaceted discipline encompassing different types, each designed to serve specific research purposes and requirements. These various types of bibliographies provide valuable tools for researchers, scholars, and readers to navigate the vast realm of literature and sources available. From comprehensive overviews to specialized focuses, the types of bibliographies offer distinct approaches to organizing, categorizing, and presenting information. Whether compiling an exhaustive list of sources, providing critical evaluations, or focusing on specific subjects or industries, these types of bibliographies play a vital role in facilitating the exploration, understanding, and dissemination of knowledge in diverse academic and intellectual domains.

As a discipline, a bibliography encompasses various types that cater to different research needs and contexts. The two main categories of bibliographies are

1. General bibliography, and 2. Special bibliography.

1.2.1. General Bibliography:

A general bibliography is a comprehensive compilation of sources covering a wide range of subjects, disciplines, and formats. It aims to provide a broad overview of published materials, encompassing books, articles, journals, websites, and other relevant resources. A general bibliography typically includes works from various authors, covering diverse topics and spanning different periods. It is a valuable tool for researchers, students, and readers seeking a comprehensive collection of literature within a specific field or across multiple disciplines. General bibliographies play a crucial role in guiding individuals in exploring a subject, facilitating the discovery of relevant sources, and establishing a foundation for further research and academic pursuits.

The general bibliography encompasses various subcategories that comprehensively cover global, linguistic, national, and regional sources. These subcategories are as follows:

• Universal Bibliography: Universal bibliography aims to compile a comprehensive list of all published works worldwide, regardless of subject or language. It seeks to encompass human knowledge and includes sources from diverse fields, cultures, and periods. Universal bibliography is a monumental effort to create a comprehensive record of the world’s published works, making it a valuable resource for scholars, librarians, and researchers interested in exploring the breadth of human intellectual output.
• Language Bibliography: Language bibliography focuses on compiling sources specific to a particular language or group of languages. It encompasses publications written in a specific language, regardless of the subject matter. Language bibliographies are essential for language scholars, linguists, and researchers interested in exploring the literature and resources available in a particular language or linguistic group.
• National Bibliography: The national bibliography documents and catalogs all published materials within a specific country. It serves as a comprehensive record of books, journals, periodicals, government publications, and other sources published within a nation’s borders. National bibliographies are essential for preserving a country’s cultural heritage, facilitating research within specific national contexts, and providing a comprehensive overview of a nation’s intellectual output.
• Regional Bibliography: A regional bibliography compiles sources specific to a particular geographic region or area. It aims to capture the literature, publications, and resources related to a specific region, such as a state, province, or local area. Regional bibliographies are valuable for researchers interested in exploring a specific geographic region’s literature, history, culture, and unique aspects.

1.2.2. Special Bibliography:

Special bibliography refers to a type of bibliography that focuses on specific subjects, themes, or niche areas within a broader field of study. It aims to provide a comprehensive and in-depth compilation of sources specifically relevant to the chosen topic. Special bibliographies are tailored to meet the research needs of scholars, researchers, and enthusiasts seeking specialized information and resources.

Special bibliographies can cover a wide range of subjects, including but not limited to specific disciplines, subfields, historical periods, geographical regions, industries, or even specific authors or works. They are designed to gather and present a curated selection of sources considered important, authoritative, or influential within the chosen subject area.

Special bibliography encompasses several subcategories that focus on specific subjects, authors, forms of literature, periods, categories of literature, and types of materials. These subcategories include:

• Subject Bibliography: Subject bibliography compiles sources related to a specific subject or topic. It aims to provide a comprehensive list of resources within a particular field. Subject bibliographies are valuable for researchers seeking in-depth information on a specific subject area, as they gather relevant sources and materials to facilitate focused research.
• Author and Bio-bibliographies: Author and bio-bibliographies focus on compiling sources specific to individual authors. They provide comprehensive lists of an author’s works, including their books, articles, essays, and other publications. Bio-bibliographies include biographical information about the author, such as their background, career, and contributions to their respective fields.
• Bibliography of Forms of Literature: This bibliography focuses on specific forms or genres of literature, such as poetry, drama, fiction, or non-fiction. It provides a compilation of works within a particular literary form, enabling researchers to explore the literature specific to their interests or to gain a comprehensive understanding of a particular genre.
• Bibliography of Materials of Particular Periods: Bibliographies of materials of particular periods compile sources specific to a particular historical period or time frame. They include works published or created during that period, offering valuable insights into the era’s literature, art, culture, and historical context.
• Bibliographies of Special Categories of Literature: This category compiles sources related to special categories or themes. Examples include bibliographies of children’s literature, feminist literature, postcolonial literature, or science fiction literature. These bibliographies cater to specific interests or perspectives within the broader field of literature.
• Bibliographies of Specific Types of Materials: Bibliographies of specific materials focus on compiling sources within a particular format or medium. Examples include bibliographies of manuscripts, rare books, visual art, films, or musical compositions. These bibliographies provide valuable resources for researchers interested in exploring a specific medium or format.

1.3 Functions of Bibliography

A bibliography serves several important functions in academic research, writing, and knowledge dissemination. Here are some key functions:

• Documentation: One of the primary functions of a bibliography is to document and record the sources consulted during the research process. By providing accurate and detailed citations for each source, it can ensure transparency, traceability, and accountability in scholarly work. It allows readers and other researchers to verify the information, trace the origins of ideas, and locate the original sources for further study.
• Attribution and Credit: The bibliography plays a crucial role in giving credit to the original authors and creators of the ideas, information, and materials used in research work. By citing the sources, the authors acknowledge the intellectual contributions of others and demonstrate academic integrity. This enables proper attribution and prevents plagiarism, ensuring ethical research practices and upholding the principles of academic honesty.
• Verification and Quality Control: It acts as a means of verification and quality control in academic research. Readers and reviewers can assess the information’s reliability, credibility, and accuracy by including a list of sources. This allows others to evaluate the strength of the evidence, assess the validity of the arguments, and determine the scholarly rigor of a work.
• Further Reading and Exploration: The bibliography is valuable for readers who wish to delve deeper into a particular subject or topic. By providing a list of cited sources, the bibliography offers a starting point for further reading and exploration. It guides readers to related works, seminal texts, and authoritative materials, facilitating their intellectual growth and expanding their knowledge base.
• Preservation of Knowledge: The bibliography contributes to the preservation of knowledge by cataloguing and documenting published works. It records the intellectual output within various fields, ensuring that valuable information is not lost over time. A bibliography facilitates the organization and accessibility of literature, making it possible to locate and retrieve sources for future reference and research.
• Intellectual Dialogue and Scholarship: The bibliography fosters intellectual dialogue and scholarship by facilitating the exchange of ideas and enabling researchers to build upon existing knowledge. By citing relevant sources, researchers enter into conversations with other scholars, engaging in a scholarly discourse that advances knowledge within their field of study.

A bibliography serves the important functions of documenting sources, crediting original authors, verifying information, guiding further reading, preserving knowledge, and fostering intellectual dialogue. It plays a crucial role in maintaining academic research’s integrity, transparency, and quality and ensures that scholarly work is built upon a solid foundation of evidence and ideas.

1.4 Importance of Bibliographic Services

Bibliographic services are crucial in academia, research, and information management. They are a fundamental tool for organizing, accessing, and preserving knowledge . From facilitating efficient research to ensuring the integrity and credibility of scholarly work, bibliographic services hold immense importance in various domains.

Bibliographic services are vital for researchers and scholars. These services provide comprehensive and reliable access to various resources, such as books, journals, articles, and other scholarly materials. By organizing these resources in a structured manner, bibliographic services make it easier for researchers to locate relevant information for their studies. Researchers can explore bibliographic databases, catalogues, and indexes to identify appropriate sources, saving them valuable time and effort. This accessibility enhances the efficiency and effectiveness of research, enabling scholars to stay up-to-date with the latest developments in their fields.

Bibliographic services also aid in the process of citation and referencing. Proper citation is an essential aspect of academic integrity and intellectual honesty. Bibliographic services assist researchers in accurately citing the sources they have used in their work, ensuring that credit is given where it is due. This not only acknowledges the original authors and their contributions but also strengthens the credibility and authenticity of the research. By providing citation guidelines, formatting styles, and citation management tools, bibliographic services simplify the citation process, making it more manageable for researchers.

Another crucial aspect of bibliographic services is their role in preserving and archiving knowledge. Libraries and institutions that provide bibliographic services serve as custodians of valuable information. They collect, organize, and preserve various physical and digital resources for future generations. This preservation ensures that knowledge is not lost or forgotten over time. Bibliographic services enable researchers, students, and the general public to access historical and scholarly materials, fostering continuous learning and intellectual growth.

Bibliographic services contribute to the dissemination of research and scholarly works. They provide platforms and databases for publishing and sharing academic outputs. By cataloguing and indexing research articles, journals, and conference proceedings, bibliographic services enhance the discoverability and visibility of scholarly work. This facilitates knowledge exchange, collaboration, and innovation within academic communities. Researchers can rely on bibliographic services to share their findings with a broader audience, fostering intellectual dialogue and advancing their respective fields.

In Summary, bibliographic services are immensely important in academia, research, and information management. They facilitate efficient analysis, aid in proper citation and referencing, preserve knowledge for future generations, and contribute to the dissemination of research. These services form the backbone of scholarly pursuits, enabling researchers, students, and professionals to access, utilize, and contribute to the vast wealth of knowledge available. As we continue to rely on information and research to drive progress and innovation, the significance of bibliographic services will only grow, making them indispensable resources in pursuing knowledge.

What is a Bibliography?

What is an annotated bibliography, introduction to the annotated bibliography.

• Writing Center
• Writer's Reference Center
• Helpful Tutorials
• the authors' names
• the titles of the works
• the names and locations of the companies that published your copies of the sources
• the dates your copies were published
• the page numbers of your sources (if they are part of multi-source volumes)

Ok, so what's an Annotated Bibliography?

An annotated bibliography is the same as a bibliography with one important difference: in an annotated bibliography, the bibliographic information is followed by a brief description of the content, quality, and usefulness of the source. For more, see the section at the bottom of this page.

What are Footnotes?

Footnotes are notes placed at the bottom of a page. They cite references or comment on a designated part of the text above it. For example, say you want to add an interesting comment to a sentence you have written, but the comment is not directly related to the argument of your paragraph. In this case, you could add the symbol for a footnote. Then, at the bottom of the page you could reprint the symbol and insert your comment. Here is an example:

This is an illustration of a footnote. 1 The number “1” at the end of the previous sentence corresponds with the note below. See how it fits in the body of the text? 1 At the bottom of the page you can insert your comments about the sentence preceding the footnote.

When your reader comes across the footnote in the main text of your paper, he or she could look down at your comments right away, or else continue reading the paragraph and read your comments at the end. Because this makes it convenient for your reader, most citation styles require that you use either footnotes or endnotes in your paper. Some, however, allow you to make parenthetical references (author, date) in the body of your work.

Footnotes are not just for interesting comments, however. Sometimes they simply refer to relevant sources -- they let your reader know where certain material came from, or where they can look for other sources on the subject. To decide whether you should cite your sources in footnotes or in the body of your paper, you should ask your instructor or see our section on citation styles.

Where does the little footnote mark go?

Whenever possible, put the footnote at the end of a sentence, immediately following the period or whatever punctuation mark completes that sentence. Skip two spaces after the footnote before you begin the next sentence. If you must include the footnote in the middle of a sentence for the sake of clarity, or because the sentence has more than one footnote (try to avoid this!), try to put it at the end of the most relevant phrase, after a comma or other punctuation mark. Otherwise, put it right at the end of the most relevant word. If the footnote is not at the end of a sentence, skip only one space after it.

What's the difference between Footnotes and Endnotes?

The only real difference is placement -- footnotes appear at the bottom of the relevant page, while endnotes all appear at the end of your document. If you want your reader to read your notes right away, footnotes are more likely to get your reader's attention. Endnotes, on the other hand, are less intrusive and will not interrupt the flow of your paper.

If I cite sources in the Footnotes (or Endnotes), how's that different from a Bibliography?

Sometimes you may be asked to include these -- especially if you have used a parenthetical style of citation. A "works cited" page is a list of all the works from which you have borrowed material. Your reader may find this more convenient than footnotes or endnotes because he or she will not have to wade through all of the comments and other information in order to see the sources from which you drew your material. A "works consulted" page is a complement to a "works cited" page, listing all of the works you used, whether they were useful or not.

Isn't a "works consulted" page the same as a "bibliography," then?

Well, yes. The title is different because "works consulted" pages are meant to complement "works cited" pages, and bibliographies may list other relevant sources in addition to those mentioned in footnotes or endnotes. Choosing to title your bibliography "Works Consulted" or "Selected Bibliography" may help specify the relevance of the sources listed.

The Importance of an Annotated Bibliography

An Annotated Bibliography is a collection of annotated citations. These annotations contain your executive notes on a source. Use the annotated bibliography to help remind you of later of the important parts of an article or book. Putting the effort into making good notes will pay dividends when it comes to writing a paper!

Good Summary

Being an executive summary, the annotated citation should be fairly brief, usually no more than one page, double spaced.

• Focus on summarizing the source in your own words.
• Avoid direct quotations from the source, at least those longer than a few words. However, if you do quote, remember to use quotation marks. You don't want to forget later on what is your own summary and what is a direct quotation!
• If an author uses a particular term or phrase that is important to the article, use that phrase within quotation marks. Remember that whenever you quote, you must explain the meaning and context of the quoted word or text. 

Common Elements of an Annotated Citation

• Summary of an Article or Book's thesis or most important points (Usually two to four sentences)
• Summary of a source's methodological approach. That is, what is the source? How does it go about proving its point(s)? Is it mostly opinion based? If it is a scholarly source, describe the research method (study, etc.) that the author used. (Usually two to five sentences)
• Your own notes and observations on the source beyond the summary. Include your initial analysis here. For example, how will you use this source? Perhaps you would write something like, "I will use this source to support my point about . . . "

A bibliography is a list of works (such as books and articles) written on a particular subject or by a particular author. Adjective : bibliographic.

Also known as a list of works cited , a bibliography may appear at the end of a book, report , online presentation, or research paper . Students are taught that a bibliography, along with correctly formatted in-text citations, is crucial to properly citing one's research and to avoiding accusations of plagiarism . In formal research, all sources used, whether quoted directly or synopsized, should be included in the bibliography.

An annotated bibliography includes a brief descriptive and evaluative paragraph (the annotation ) for each item in the list. These annotations often give more context about why a certain source may be useful or related to the topic at hand.

• Etymology:  From the Greek, "writing about books" ( biblio , "book", graph , "to write")
• Pronunciation:  bib-lee-OG-rah-fee

Examples and Observations

"Basic bibliographic information includes title, author or editor, publisher, and the year the current edition was published or copyrighted . Home librarians often like to keep track of when and where they acquired a book, the price, and a personal annotation, which would include their opinions of the book or of the person who gave it to them" (Patricia Jean Wagner, The Bloomsbury Review Booklover's Guide . Owaissa Communications, 1996)

Conventions for Documenting Sources

"It is standard practice in scholarly writing to include at the end of books or chapters and at the end of articles a list of the sources that the writer consulted or cited. Those lists, or bibliographies, often include sources that you will also want to consult. . . . "Established conventions for documenting sources vary from one academic discipline to another. The Modern Language Association (MLA) style of documentation is preferred in literature and languages. For papers in the social sciences the American Psychological Association (APA) style is preferred, whereas papers in history, philosophy, economics, political science, and business disciplines are formatted in the Chicago Manual of Style (CMS) system. The Council of Biology Editors (CBE) recommends varying documentation styles for different natural sciences." (Robert DiYanni and Pat C. Hoy II, The Scribner Handbook for Writers , 3rd ed. Allyn and Bacon, 2001)

APA vs MLA Styles

There are several different styles of citations and bibliographies that you might encounter: MLA, APA, Chicago, Harvard, and more. As described above, each of those styles is often associated with a particular segment of academia and research. Of these, the most widely used are APA and MLA styles. They both include similar information, but arranged and formatted differently.

"In an entry for a book in an APA-style works-cited list, the date (in parentheses) immediately follows the name of the author (whose first name is written only as an initial), just the first word of the title is capitalized, and the publisher's full name is generally provided.

APA Anderson, I. (2007). This is our music: Free jazz, the sixties, and American culture . Philadelphia: University of Pennsylvania Press.

By contrast, in an MLA-style entry, the author's name appears as given in the work (normally in full), every important word of the title is capitalized, some words in the publisher's name are abbreviated, the publication date follows the publisher's name, and the medium of publication is recorded. . . . In both styles, the first line of the entry is flush with the left margin, and the second and subsequent lines are indented.

Finding Bibliographic Information for Online Sources

"For Web sources, some bibliographic information may not be available, but spend time looking for it before assuming that it doesn't exist. When information isn't available on the home page, you may have to drill into the site, following links to interior pages. Look especially for the author's name, the date of publication (or latest update), and the name of any sponsoring organization. Do not omit such information unless it is genuinely unavailable. . . . "Online articles and books sometimes include a DOI (digital object identifier). APA uses the DOI, when available, in place of a URL in reference list entries." (Diana Hacker and Nancy Sommers, A Writer's Reference With Strategies for Online Learners , 7th ed. Bedford/St. Martin's, 2011)

Harvard Style Bibliography | Format & Examples

Published on 1 May 2020 by Jack Caulfield . Revised on 7 November 2022.

In Harvard style , the bibliography or reference list provides full references for the sources you used in your writing.

• A reference list consists of entries corresponding to your in-text citations .
• A bibliography sometimes also lists sources that you consulted for background research, but did not cite in your text.

The two terms are sometimes used interchangeably. If in doubt about which to include, check with your instructor or department.

The information you include in a reference varies depending on the type of source, but it usually includes the author, date, and title of the work, followed by details of where it was published. You can automatically generate accurate references using our free reference generator:

Sources are alphabetised by author last name. The heading ‘Reference list’ or ‘Bibliography’ appears at the top.

Each new source appears on a new line, and when an entry for a single source extends onto a second line, a hanging indent is used:

Reference list or bibliography entries always start with the author’s last name and initial, the publication date and the title of the source. The other information required varies depending on the source type. Formats and examples for the most common source types are given below.

• Entire book
• Book chapter
• Translated book
• Edition of a book

Journal articles

• Print journal
• Online-only journal with DOI
• Online-only journal without DOI
• General web page
• Online article or blog
• Social media post

Newspapers and magazines

• Newspaper article
• Magazine article

When a source has up to three authors, list all of them in the order their names appear on the source. If there are four or more, give only the first name followed by ‘ et al. ’:

Sometimes a source won’t list all the information you need for your reference. Here’s what to do when you don’t know the publication date or author of a source.

Some online sources, as well as historical documents, may lack a clear publication date. In these cases, you can replace the date in the reference list entry with the words ‘no date’. With online sources, you still include an access date at the end:

When a source doesn’t list an author, you can often list a corporate source as an author instead, as with ‘Scribbr’ in the above example. When that’s not possible, begin the entry with the title instead of the author:

Though the terms are sometimes used interchangeably, there is a difference in meaning:

• A reference list only includes sources cited in the text – every entry corresponds to an in-text citation .
• A bibliography also includes other sources which were consulted during the research but not cited.

In Harvard referencing, up to three author names are included in an in-text citation or reference list entry. When there are four or more authors, include only the first, followed by ‘ et al. ’

In Harvard style referencing , to distinguish between two sources by the same author that were published in the same year, you add a different letter after the year for each source:

• (Smith, 2019a)
• (Smith, 2019b)

Add ‘a’ to the first one you cite, ‘b’ to the second, and so on. Do the same in your bibliography or reference list .

To create a hanging indent for your bibliography or reference list :

• Highlight all the entries
• Click on the arrow in the bottom-right corner of the ‘Paragraph’ tab in the top menu.
• In the pop-up window, under ‘Special’ in the ‘Indentation’ section, use the drop-down menu to select ‘Hanging’.
• Then close the window with ‘OK’.

Cite this Scribbr article

If you want to cite this source, you can copy and paste the citation or click the ‘Cite this Scribbr article’ button to automatically add the citation to our free Reference Generator.

Citing: Bibliographies

• Bibliographies
• Annotated Bibliographies

Common Knowledge

If something is common knowledge, then you don't have to cite it.  But, that leaves a major question:

What Qualifies as Common Knowledge?

One way to get an idea if something is common knowledge is to ask a couple of your friends if they know it.  If all of them know it, it is probably common knowledge (unless all of your friends happen to have done extensive research on the subject).

Also, here are some guidelines to determining what is common knowledge.  But, remember, not everyone agrees on what counts as common knowledge.  It is always better to cite something than to risk plagiarizing.

 Common knowledge also depends on the field you are working in.  For example, symptoms of schizophrenia may be common knowledge to  psychologists, and thus not need citing, but it may not be common knowledge for a biologist.

If you are still in doubt, cite it.

It is better to cite too much than to not cite enough.

A citation is a reference to another source.

Who Needs to Include a Bibliography?

Everyone who uses the ideas, research, or writing of another person in his or her own work needs to include a bibliography as a part of that work.

This includes students, researchers, authors, professors, academicians, and Klingons.

What Is a Bibliography?

A bibliography is a list of all the sources that you reference in your paper. 

The reader should be able to find every source that you mention at the end of your paper in your bibliography. 

It can also be called the “Works Cited” or “References,” depending on the format (MLA, APA, Chicago, Turabian).

When Should You Include a Bibliography?

Include a bibliography every time you use something that someone else produced.  This includes quotes, paraphrases, ideas, and facts. 

If you did not come up with it, and if it is not common knowledge, you need to cite its author in your bibliography.

When Should You Begin Working on Your Bibliography?

Begin working on your bibliography as soon as you begin your research.  Keep track of the sources you use and the page numbers of passages that you quote or paraphrase.  This will save you time later!

Where Does Your Bibliography Go?

A bibliography should be included at the end of your paper, with the title “Works Cited,” “Bibliography,” or “References,” depending on what format you are using for your paper (MLA, APA, Chicago, etc).

The page numbering of your paper should continue into the bibliography.  Thus, if the last page of your paper is page 11, the first page of your bibliography will be page 12.

Why Do You Need to Include a Bibliography?

It is important to include a bibliography so that you give credit where it is due.  If you use any idea or research that is not your own, you must acknowledge the scholarship of the person who created that idea or research.

If you don’t properly acknowledge other works that you have used, you will be guilty of plagiarism, which not only will lower your grade for the class, but is illegal.

A bibliography shows that your work is supported by good research.  The reader of your paper can see what resources you used to produce your paper, and thereby see that there is support for what you have said.

How Do You Create a Bibliography?

There are many different styles of writing, and each has its own nuanced specifications for creating a bibliography.  They all, however, require some basic information, such as the name of the author and the name of the work.  Each format has different rules for in-text citations, as well as the “Works Cited” page.  Use the following resources to find out how to do a bibliography in the style your paper requires.

31 Bibliography

Annotated bibliography.

A  bibliography  is an alphabetized list of sources showing the author, date, and publication information for each source.

An  annotation  is like a note; it’s a brief paragraph that explains what the writer learned from the source.

Annotated bibliographies combine bibliographies and brief notes about the sources.

Writers often create annotated bibliographies as a part of a research project, as a means of recording their thoughts and deciding which sources to actually use to support the purpose of their research. Some writers include annotated bibliographies at the end of a research paper as a way of offering their insights about the source’s usability to their readers.

Instructors in college often assign annotated bibliographies as a means of helping students think through their source’s quality and appropriateness to their research question or topic.  (23)

Formatting the Annotated Bibliography

The  citations  (bibliographic information – title, date, author, publisher, etc.) in the annotated bibliography are formatted using the particular style manual (APA, MLA, Chicago, etc.) that your discipline requires.

Annotations  are written in paragraph form, usually 3-7 sentences (or 80-200 words). Depending on your assignment your annotations will generally include the following:

• Summary:  Summarize the information given in the source. Note the intended audience. What are the main arguments? What is the point of this book or article? What topics are covered? If someone asked what this article/book is about, what would you say?
• Evaluate/Assess:  Is this source credible? Who wrote it? What are their credentials? Who is the publisher? Is it a useful source? How does it compare with other sources in your bibliography? Is the information reliable? Is this source biased or objective? What is the goal of this source?
• Reflect/React:  Once you’ve summarized and assessed a source, you need to ask how it fits into your research. State your reaction and any additional questions you have about the information in your source. Was this source helpful to you? How does it help you shape your argument? How can you use this source in your research project? Has it changed how you think about your topic? Compare each source to other sources in your annotated bibliography in terms of its usefulness and thoroughness in helping answer your research question.  (24)

Annotated Bibliography Examples

In the following examples, the bold font indicates the reflection component of the annotation that is sometimes required in an assignment.

APA style 6  th  edition for the journal citation:

Waite, L. J., Goldschneider, F. K., & Witsberger, C. (1986). Nonfamily living and the erosion of traditional family orientations among young adults.  American Sociological Review  , 51, 541-554.

The authors, researchers at the Rand Corporation and Brown University, use data from the National Longitudinal Surveys of Young Women and Young Men to test their hypothesis that nonfamily living by young adults alters their attitudes, values, plans, and expectations, moving them away from their belief in traditional sex roles. They find their hypothesis strongly supported in young females, while the effects were fewer in studies of young males. Increasing the time away from parents before marrying increased individualism, self-sufficiency, and changes in attitudes about families.  In contrast, an earlier study by Williams cited below shows no significant gender differences in sex role attitudes as a result of nonfamily living.  (25)

MLA 8 style for a website citation:

Anderson, L.V. “Can You Libel Someone on Twitter?” Slate.com, The Slate Group, A Graham Holdings. Company, 26 Nov. 2012, http://www.slate.com/articles/technology/explainer/2012/11/libel_on_twitter_you_can_be_sued_for_libel_for_what_you_write_on_facebook.html . Accessed 2 Apr. 2018.

This article provides an overview of defamation law in the United States compared to the United Kingdom, in layman’s terms. It also explains how defamation law applies to social media platforms and individuals who use social media. Libelous comments posted on social media can be subject to lawsuit, depending on the content of the statement, and whether the person is a public or private figure. The article is found on the website, Slate.com, which is a web-based daily magazine that focuses on general interest topics. While the writer’s credentials are unavailable, she does thank Sandra S. Baron, Executive Director of the Media Law Resource Center and Jeff Hermes, director of the Digital Media Law Project for providing information. She also links to the United States laws that she cites.  I would use the article to compare United States law to United Kingdom law and for background information.  (1)

Information creation is a process. Scholars produce information in the forms of peer-reviewed journal articles, books, and conference presentations, to name a few. As a student researcher, you will be expected to create research projects such as essays, reports, visual presentations, and annotated bibliographies. Most scholarly writing makes an argument—whether it is to persuade your readers that your claim is true or to act on it. In order to create a sound argument, you must gather sources that will argue and counter-argue your claims.

When creating an argument, the researcher typically organizes their report or presentation with the claim/thesis at the beginning, which answers their research question. Then they provide reasons and supporting evidence to validate their claim. They acknowledge and respond to counter-arguments by citing sources that disagree with them, and refuting or conceding those counter-claims. Their conclusion restates their thesis and discusses why their research is important to the scholarly conversation, as well as potential areas for further research.

A Roman numeral outline is one way to organize your argument before you begin writing. It helps to identify sources for each section of your outline, so you know if you need further research to support your argument.

An annotated bibliography is one way to present research, and can be used as a cumulative assignment, or a precursor to your actual research paper. A good annotated bibliography will provide a variety of sources that met all your research needs—background, evidence, argument, and method. In other words, you should be able to take your annotated bibliography and write a complete research report based on those sources.  (1)

What is a bibliography?

A bibliography is a list of works on a subject or by an author that were used or consulted to write a research paper, book or article. It can also be referred to as a list of works cited. It is usually found at the end of a book, article or research paper. 

Gathering Information

Regardless of what citation style is being used, there are key pieces of information that need to be collected in order to create the citation.

For books and/or journals:

• Author name
• Title of publication 
• Article title (if using a journal)
• Date of publication
• Place of publication
• Volume number of a journal, magazine or encyclopedia
• Page number(s)

For websites:

• Author and/or editor name
• Title of the website
• Company or organization that owns or posts to the website
• URL (website address)
• Date of access 

This section provides two examples of the most common cited sources: a print book and an online journal retrieved from a research database. 

Book - Print

For print books, bibliographic information can be found on the  TITLE PAGE . This page has the complete title of the book, author(s) and publication information.

The publisher information will vary according to the publisher - sometimes this page will include the name of the publisher, the place of publication and the date.

For this example :  Book title: HTML, XHTML, and CSS Bible Author: Steven M. Schafer Publisher: Wiley Publications, Inc.

If you cannot find the place or date of publication on the title page, refer to the  COPYRIGHT PAGE  for this information. The copyright page is the page behind the title page, usually written in a small font, it carries the copyright notice, edition information, publication information, printing history, cataloging data, and the ISBN number.

For this example : Place of publication: Indianapolis, IN Date of publication: 2010

Article - Academic OneFile Database

In the article view:

Bibliographic information can be found under the article title, at the top of the page. The information provided in this area is  NOT  formatted according to any style.

Citations can also be found at the bottom of the page; in an area titled  SOURCE CITATION . The database does not specify which style is used in creating this citation, so be sure to double check it against the style rules for accuracy.

Article - ProQuest Database

Bibliographic information can be found under the article title, at the top of the page. The information provided in this area is  NOT  formatted according to any style. 

Bibliographic information can also be found at the bottom of the page; in an area titled  INDEXING . (Not all the information provided in this area is necessary for creating citations, refer to the rules of the style being used for what information is needed.)

Other databases have similar formats - look for bibliographic information under the article titles and below the article body, towards the bottom of the page.
