When you write a paper or a book, it's important to include a bibliography. A bibliography tells your reader what sources you've used. It lists all the books, articles, and other references you cited in or used to inform your work. Bibliographies are typically formatted according to one of three styles: American Psychological Association (APA) for scientific papers, Modern Language Association (MLA) for humanities papers, and Chicago Manual of Style (CMS) for the social sciences. Make sure you always check with your superior - whether a professor or boss - about which style they prefer.

Sample Bibliographies

Writing an APA Bibliography

• For example, if the author's name for a source is "John Adams Smith," you would list him as "Smith, J.A.," before listing the title of his piece.

• For example, if one source has twelve authors, and the seventh author is "Smith, J.A." and the twelfth is "Timothy, S.J.," you would list the first six authors, then write "Smith, J.A. ...Timothy, S.J."

• For example, if you have a World Health Organization Report without an author as one of your sources, you would write, "World Health Organization, "Report on Development Strategies in Developing Nations," July 1996."

• For example, an article citation might look like this: Jensen, O. E. (2012). "African Elephants." Savannah Quarterly , 2(1), 88.
• If the periodical the article comes from always begins with page number 1 (these types of periodicals are called “paginated by issue” periodicals, you should include the full page range of the article.
• If the article was retrieved online, end the citation with the words "Retrieved from" followed by the web address.

• Example: Worden, B. L. (1999). Echoing Eden. New York, New York: One Two Press.
• If the title is more than one word long and doesn’t contain any proper nouns, only the first word should be capitalized. Only the first letter of any subtitle should be capitalized as well.

• For example, a cited website might look like this: Quarry, R. R. (May 23, 2010). Wild Skies. Retrieved from https://wildskies.com.
• If no author is available, just start with the title. If no date is available, write "n.d."

Writing a MLA Bibliography

• You shouldn’t use an author’s title or degrees when listing their names in your bibliography. This is true even if they are listed that way on the source.

• For example, a book citation might look like this: Butler, Olivia. Parable of the Flower. Sacramento: Seed Press, 1996.

• For example, an article published in a scholarly journal might look like this: Green, Marsha. "Life in Costa Rica." Science Magazine vol. 1, no. 4, Mar 2013: 1-2.
• If you’re citing an article in a newspaper, you only need the name of the newspaper, followed by the date it was published, and the page number. A citation for that might look like this: Smith, Jennifer. “Tiny Tim Wins Award.” New York Times, 24 Dec 2017, p. A7.

• For example, a website citation might look like this: Jong, June. "How to Write an Essay." Writing Portal. 2 Aug. 2012. University of California. 23 Feb. 2013. <https://writingportal.com>
• Some websites, particularly academic ones, will have what’s called a DOI (digital object identifier). Write “doi:” in front of this number in place of the website’s url if a DOI is available.

Writing a CMS Bibliography

• Example: Skylar Marsh. "Walking on Water." Earth Magazine 4(2001): 23.

• For example, a book entry might look like this: Walter White. Space and Time . New York: London Press, 1982

• Example: University of California. "History of University of California." Last modified April 3, 2013. https://universityofcalifornia.com.
• Unless there is a publication date for the website you’re citing, you don’t need to include an access date. If you do have an access date, it goes at the end of the citation.

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 . . . "

What Is a Bibliography?

A bibliography is a list of books, scholarly  articles , speeches, private records, diaries, interviews, laws, letters, websites, and other sources you use when researching a topic and writing a paper. The bibliography appears at the end.

The main purpose of a bibliography entry is to give credit to authors whose work you've consulted in your research. It also makes it easy for a reader to find out more about your topic by delving into the research that you used to write your paper. In the academic world, papers aren't written in a vacuum; academic journals are the way new research on a topic circulates and previous work is built upon.

Bibliography entries must be written in a very specific format, but that format will depend on the particular style of writing you follow. Your teacher or publisher will tell you which style to use, and for most academic papers it will be either MLA , American Psychological Association (APA), Chicago (author-date citations or footnotes/endnotes format), or Turabian style .

The bibliography is sometimes also called the references, works cited, or works consulted page.

Components of a Bibliography Entry

Bibliography entries will compile:

• Authors and/or editors (and translator, if applicable)
• Title of your source (as well as edition, volume, and the book title if your source is a chapter or article in a multi-author book with an editor)
• Publication information (the city, state, name of the publisher, date published, page numbers consulted, and URL or DOI, if applicable)
• Access date, in the case of online sources (check with the style guide at the beginning of your research as to whether you need to track this information)

Order and Formatting

Your entries should be listed in alphabetical order by the last name of the first author. If you are using two publications that are written by the same author, the order and format will depend on the style guide.

In MLA, Chicago, and Turabian style, you should list the duplicate-author entries in alphabetical order according to the title of the work. The author's name is written as normal for his or her first entry, but for the second entry, you will replace the author's name with three long dashes. 

In APA style, you list the duplicate-author entries in chronological order of publication, placing the earliest first. The name of the author is used for all entries.

For works with more than one author, styles vary as to whether you invert the name of any authors after the first. Whether you use title casing or sentence-style casing on titles of sources, and whether you separate elements with commas or periods also varies among different style guides. Consult the guide's manual for more detailed information.

Bibliography entries are usually formatted using a hanging indent. This means that the first line of each citation is not indented, but subsequent lines of each citation are indented. Check with your instructor or publication to see if this format is required, and look up information in your word processor's help program if you do not know how to create a hanging indent with it.

Chicago's Bibliography vs. Reference System

Chicago has two different ways of citing works consulted: using a bibliography or a references page. Use of a bibliography or a references page depends on whether you're using author-date parenthetical citations in the paper or footnotes/endnotes. If you're using parenthetical citations, then you'll follow the references page formatting. If you're using footnotes or endnotes, you'll use a bibliography. The difference in the formatting of entries between the two systems is the location of the date of the cited publication. In a bibliography, it goes at the end of an entry. In a references list in the author-date style, it goes right after the author's name, similar to APA style.
