Articles

Article Icon

 

When citing a scholarly article from a database if you can not find a DOI, a permalink or a nondatabase URL then you do not need to provide a link in APA 9th edition, unless requested by your professor.   

Some example citations are below, from the Purdue OWL APA Guide. Follow the link for more examples!

Basic Newspaper Citation 

Author Last Name, Author First Initial. (Publication Year, Month Day). Title of the article. Newspaper Title. Page number, if known. DOI

Basic Scholarly Journal Article Citation 

Author Last Name, Author First Initial. (Publication Year). Title of the article. Journal Title, Volume #(Issue #), page numbers. DOI

If an journal article has an article number instead of a page number include the word "Article" and then the article number.

Website

Website Icon

 

In APA style, 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. In APA style, you only need to include the date of access if the page's content will probably change over time (i.e. a wiki page).

Basic Website Citation

Authors Last name, Authors First Initial. (Publication Year, Month Date). Title of page. Site name. URL

 

If the resource was written by a group or organization, use the name of the group/organization as the author. If the author and site name are the same, omit the site name from the citation.

Group name. (Publication Year, Month Date). Title of page. Site name. URL

Digital Resources


Citing personal photos, digital files, or other electronic resources can be confusing. The important thing to remember is that everything you use for academic or professional work, even if you made it yourself, does need to be cited - every time!

Some URL Notes from Purdue OWL:

Link Icon

  • Many scholarly journal articles found in databases include a DOI (digital object identifier). If a DOI is available, cite the DOI number instead of the URL.
  • Online newspapers and magazines sometimes include a permalink, which is a shortened, stable version of a URL. Look for a “share” or “cite this” button to see if a source includes a permalink. If you can find a permalink, use that instead of a URL.

If you have a question or need to cite something not listed here, schedule a consultation with a librarian!

Digital Resources in APA Style: How Do I Cite...

Visit the Purdue OWL Pages on citing Audiovisual Media and Electronic Sources in APA for more examples!

If the author’s name is the same as the uploader, only cite the author once. If the author is different from the uploader, cite the author’s name before the title.Play Button Icon

AI Generated Content

 

Generative AI is still a new technology as such the rules around citing it are still evolving. This guide lays out recommendations made by APA for how to cite content created by generative AI. 

Always before using AI in a project check with your professor. According to the the Undergraduate Academic Honor Code of Oxford College:

Using an artificial intelligence program to generate any content for any assignment (including, but not limited to examinations, papers, homework, and creative work) constitutes plagiarism and is a violation of the Honor Code unless students acknowledge in the assignment the extent to which an artificial intelligence program contributed to their work and outside resources are permitted for the assignment.

 


AI Generated Text

In APA style it you should describe how and where you used AI generated content in your work. For example in your introduction or methodology sections you might describe how you used AI.

APA recommends that you provide the prompt used and any relevant text that was generated in response.

Example:

Gemini when prompted with " In 200 words describe the symbolism of Momento Mori in European renaissance art" generated text describing how "Memento mori, Latin for "remember you must die," was a potent theme in Renaissance art." (Google DeepMind, 2024). 

Reference:

Google DeepMind. (2024) Gemini [multimodal large language model]. https://gemini.google.com/app

For more information on citing AI Generated Content see the APA Style blog post on AI.

 

In-Text Citations

APA uses parenthetical citations for in-text citation. Include the author's last name and the date of the work. Typically you put this at the end of the sentence just before the period.  

 

Format:

(author's last name, date)  

Example:

Scholars argue about who is the original leader of the Justice League, but one scholar is convinced it is Superman (Kent, 1938).

In APA, only include the page number if you are directly quoting a source. (If quoting more than one page, use pp. instead of p.).

Format:

(author's last name, date, p. page number)  

Example:

While impressive, some claim that Batman's skills are "overblown by the Gotham police" and his actual contributions to the recent decrease in crime in the city are minimal (Kent, 1938, p. 12).

To cite more than one source, put a semicolon between the two sources' citations.

Format:

(author's last name, date; author's last name, date) 

Example:

Despite the disagreement, both authors agree that global crime has decreased thanks to the effort of the Justice League (Kent, 1938; Wayne, 1939).
