Welcome to the Purdue OWL
This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.
Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.
APA (American Psychological Association) style is most commonly used to cite sources within the social sciences. This resource, revised according to the 6 th edition, second printing of the APA manual, offers examples for the general format of APA research papers, in-text citations, endnotes/footnotes, and the reference page. For more information, please consult the Publication Manual of the American Psychological Association , (6 th ed., 2 nd printing).
Note: This page reflects APA 6, which is now out of date. It will remain online until 2021, but will not be updated. The equivalent APA 7 page can be found here .
Please note: Some electronic citations necessitate the use of brackets; APA style dictates that brackets should directly surround their content without spaces (e.g., [bracketed content] should look like this). When possible, include the year, month, and date in references. If the month and date are not available, use the year of publication. Please note, too, that the OWL still includes information about print sources and databases for those still working with these sources .
Webpage or Piece of Online Content
Individual webpages and documents hosted online are cited similarly to print content. Note, however, that the URL is typically included at the end of the entry. The URL may, at the author's discretion, be left as an active link. Include additional information (like translators, editors, first edition publication date, and so on) as you would for print sources.

Article From an Online Periodical
Online articles follow the same guidelines for printed articles. Include all information the online host makes available, including an issue number in parentheses.

Online Scholarly Journal Article: Citing DOIs
Please note : In August of 2011 the formatting recommendations for DOIs changed. DOIs are now rendered as an alpha-numeric string which acts as an active link. According to The APA Style Guide to Electronic References, 6 th edition , you should use the DOI format which the article appears with. So, if it is using the older numeric string, use that as the DOI. If, however, it is presented as the newer alpha-numeric string, use that as the DOI. The Purdue OWL maintains examples of citations using both DOI styles.
Because online materials can potentially change URLs, APA recommends providing a Digital Object Identifier (DOI), when it is available, as opposed to the URL. DOIs are an attempt to provide stable, long-lasting links for online articles. They are unique to their documents and consist of a long alphanumeric code. Many—but not all—publishers will provide an article's DOI on the first page of the document.
Note that some online bibliographies provide an article's DOI but may "hide" the code under a button which may read "Article" or may be an abbreviation of a vendor's name like "CrossRef" or "PubMed." This button will usually lead the user to the full article which will include the DOI. Find DOI's from print publications or ones that go to dead links with CrossRef.org's "DOI Resolver," which is displayed in a central location on their home page.

Article From an Online Periodical with no DOI Assigned
Online scholarly journal articles without a DOI require the URL of the journal home page. Remember that one goal of citations is to provide your readers with enough information to find the article; providing the journal home page aids readers in this process.

Article from a Database
Please note: APA states that including database information in citations is not necessary because databases change over time (p. 192). However, the OWL still includes information about databases for those users who need database information.
When referencing a print article obtained from an online database (such as a database in the library), provide appropriate print citation information (formatted just like a "normal" print citation would be for that type of work). By providing this information, you allow people to retrieve the print version if they do not have access to the database from which you retrieved the article. You can also include the item number or accession number or database URL at the end, but the APA manual says that this is not required.
If you are citing a database article that is available in other places, such as a journal or magazine, include the homepage's URL. You may have to do a web search of the article's title, author, etc. to find the URL.
For articles that are easily located, do not provide database information. If the article is difficult to locate, then you can provide database information. Only use retrieval dates if the source could change, such as Wikis. For more about citing articles retrieved from electronic databases, see pages 187-192 of the Publication Manual.

If you only cite an abstract but the full text of the article is also available, cite the online abstract as any other online citations, adding "[Abstract]" after the article or source name. However, if the full text is not available, you may use an abstract that is available through an abstracts database as a secondary source.

Electronic books may include books found on personal websites, databases, or even in audio form. Use the following format if the book you are using is only provided in a digital format or is difficult to find in print. If the work is not directly available online or must be purchased, use "Available from," rather than "Retrieved from," and point readers to where they can find it. For books available in print form and electronic form, include the publish date in parentheses after the author's name. For references to e-book editions, be sure to include the type and version of e-book you are referencing (e.g., "[Kindle DX version]"). If DOIs are available, provide them at the end of the reference.

To cite Kindle (or other e-book formats) you must include the following information: the author, date of publication, title, e-book version, and either the Digital Object Identifier (DOI) number, or the place where you downloaded the book. Please note that the DOI/place of download is used in-place of publisher information.

YouTube Video or Video Blog Entry
Online videos are cited similarly to the other types of digital media described above. However, because the creators of digital videos often go by pseudonymous screen names, this information is included after the author's name.
The general format is as follows:

Here, the "author" is the person who uploaded the video file. The screen name should be spelled and capitalized exactly as it appears, even if it does not observe standard spelling and capitalization rules.
If no author name is available, or if the author's name is identical to the username, leave it out. In this case, do not put the username in brackets.

Recommendation by UptoDate
UptoDate recommends that you cite the UpToDate topic as a chapter in a book titled UpToDate. There are no page numbers to cite, and the publication year for any topic should be the current year.
The example below is provided by UptoDate :
Marion DW. Pacing the diaphragm: Patient selection, evaluation, implantation, and complications. In: UpToDate , Post TW (Ed), UpToDate, Waltham, MA. (Accessed on January 04, 2018.)
Recommendation by the DMU library
However, the corporate recommendation does not necessarily follow the citation style guidelines that you may need for your class assignments or for publication. We recommend you cite Uptodate as a chapter in an ebook, modified to the appropriate style guidelines.
APA 10th edition example:
Author, A. A., & Author, B. B. (Year of publication). Title of chapter. In A. A. Editor & B. B. Editor (Eds.), Title of book . Available from: http:///
Using the below UptoDate topic below as an example, here is the recommended APA citation format you would follow when you need to cite three to seven authors :
Borody, T.J., Leis, S., Pang, G., & Wettstein, A.R. (2013). Fecal microbiota transplantation in the treatment of recurrent Clostridium difficile infection. In T.W. Post, P. Rutgeerts, & S. Grover (Eds.), UptoDate . Available from http://www.uptodate.com/contents/fecal-microbiota-transplantation-in-the-treatment-of-recurrent-clostridium-difficile-infection?source=search_result&search=fecal+transplant&selectedTitle=1~7
Finally, in regards to the recommended editor, while UptoDate lists a specific individual on their website that they would like to credit, this individual is not necessarily listed as an editor on the UptoDate topic pages. In deference to the company, we recommend listing this individual as one of the editors in your citation. But we believe that authorship and editorship should be attributed to all names on an UptoDate topic. Our example citation reflects this guideline.
For more information, the rules for citing editors are listed in Section 6.27 Author and Editor Information of the APA's Publication Manual, 6th Edition.
Note: The Purdue OWL site also states that in the case of electronic books, "If the work is not directly available online or must be purchased, use "Available from," rather than "Retrieved from", and point readers to where they can find it. For books available in print form and electronic form, include the publish date in parentheses after the author's name." Since UptoDate is a licensed resource, not available to the general public, the library example reflects this recommendation.

APA Reference Examples for: StatPearls, UpToDate, DynaMedex
Tips for citing point of care tools & databases in APA 7th edition (Chapter 10.1, p. 319).
- Authors: OFTEN individual authors are NOT included on point-of-care tools. When that's the case, use the point-of-care tool as the name of the "author." Editors should not be listed in the area of "authors" unless you are referencing a book.
- Year/Date: To create the "date" for the reference, use the date that the page or reference article was last updated.
- Retrieval dates : remember it's important to use a retrieval date in the source information for point-of-care tools BECAUSE they are constantly updated and the old information IS NOT archived (or easily able to locate again).
- Information that is constantly updated without an archive. Articles contained in point of care tools are ONLY available in the database in which they came from AND the information is constantly updated over time. Because of this, it's often important to include a retrieval date.
Important Notes on StatPearls:
- "StatPearls material is always a challenging reference type because people come across StatPearls materials in the National Library of Medicine database (and APA references USUALLY do not cite databases), but the material is usually also available on the StatPearls website (APA Style Expert, personal communication, April 4, 2023, para 1)."
- "(Additionally,) StatPearls is often the developer and original publisher of the material, which makes the UpToDate reference example the closest exemplar from the Publication Manual (APA Style Expert, personal communication, April 4, 2023)."
- "Further, the StatPearls website clarifies the roles of the people listed in the byline on PubMed, and there's usually at least one editor among them, even though editors would not be included in the author element of reference with named authors (APA Style Expert, personal communication, April 4, 2023, para 1)."
- "Therefore, although it is admittedly not necessarily the most intuitive way to format the reference, here is what APA style would prefer for your example (APA Style Expert, personal communication, April 4, 2023, para 1)."
- "However, given that (some) StatPearls articles are also only available through the National Library of Medicine, the reference format should follow the example on page 337/example number 73, for the informally published work from PubMed Central (APA Style Expert, personal communication, April 4, 2023, para 1)."
- In the first reference StatPearls is in italics, since APA recognizes it from this website as a formal publisher and therefore as a proper noun . In the second reference, the name of the article is in italics, since on most websites the reference title is placed in italics.

How do I cite drug information from UpToDate?
APA 7th edition provides an example for citing articles in UpToDate ; however, drug information is often proprietary and uses the group author element and missing information , or n.d. for "no date." Check out the example below for Aspirin: Drug information .
Reference List Example:
Lexicomp. (n.d.). Aspirin: Drug information. UpToDate . Retrieved March 12, 2020, from https://www-uptodate-com.libproxy.csudh.edu/contents/aspirin-drug-information
Here’s a brief explanation of each element in the reference citation:
- Author – Since drug information is provided by a company rather than associated with any individual authors, use the name of the drug company (e.g. Lexicomp) as a group author .
- Date – Since there is no specific date of publication listed, use n.d. for "no date."
- Title – Use the title of the drug information article as it appears.
- Source – Typically, database information isn’t necessary in an APA 7th edition. However, UpToDate includes original, proprietary content so it would be listed in the source element and italicized.
- Retrieval Date – Typically, retrieval dates aren't necessary in APA 7th edition. However, since drug information provided in this database is designed to change over time, you would still include a retrieval date using the Month, Day Year format of when you accessed the information.
- URL – Include the CSUDH Library subscription link to UpToDate content.

The official source for APA citing is the APA website , which has many examples and is easy to use. You can also contact them with APA Style Help (it may not be immediate help).
You can also use the library's APA website, which you can access from the Library Citation Support Guide . This is kept as up-to-date as possible and contains information and examples knowingly used at SaskPolytech. Check the tabs on the left under 'in text citations' and/or 'references list' for examples.
The Purdue Owl is still usable but it is best to use the above sources.

Citing UpToDate and Cochrane Reviews in APA Style
Whenever possible, it's a good idea to cite the original research evidence (as referenced within review articles or databases like UpToDate and Cochrane Library). There are times, however, when you may want to cite the UpToDate or Cochrane summary. In that case, the citation formats below are recommended.
An example of a citation for an UpToDate review:
Robertson, R. P. , & Udler, M. S. (2021). Pathogenesis of type 2 diabetes mellitus. UptoDate . Retrieved September 4, 2023,
An example of a citation for a Cochrane Library review:
Mehrholz, J., Pohl, M., Platz, T., Kugler, J., & Elsner, B. (2018). Electromechanical and robot-assisted arm training for improving activities of daily living, arm function, and arm muscle strength after stroke. Cochrane Database of Systematic Reviews . https://doi.org/10.1002/14651858.CD006876.pub5
Citing an entry from Essential Evidence Plus
Like UpToDate, Essential Evidence Plus is a subscription database with content reviewed and updated regularly. A retrieved date is also included to alert a reader that the information may have changed since it was retrieved. The citation format below is recommended:
Robertson, S., Song, C., Smilnak, T., & O’Connor, N. (2023). Diabetes mellitus (type 2). Essential Evidence Plus . Retrieved September 4, 2023, from https://www.essentialevidenceplus.com/content/eee/127
Citing the Merck Manual Professional Version
Citations from the Merck Manual follow the APA Publication Manual guidelines for an entry in an encyclopedia or reference work. Because the Merck Manual is updated regularly, a Retrieved date is also included to alert a reader that the information may have changed since it was retrieved.
Ortega, V. E., & Genese, F. (2022). Asthma. In Merck Manal Professional Version . Merck & Co., Inc. Retrieved September 4, 2023, from https://www.merckmanuals.com/professional/pulmonary-disorders/asthma-and-related-disorders/asthma
