APA in-text citations

One of the main quirks of APA style concerns how you format in-text citations based on the number of authors for that resource (journal, book, website, etc.). The table below provides a quick summary of the main formatting variations.

• If a work on a website has no author, consider first if it is a source worthy of using in your research.
• Put the title first, followed by a period and alphabetize by the first significant word of the title (i.e., ignore A, An, or The at the beginning of the title). Alphabetize numbers as if they were spelled out (e.g., 200 would come after Tuchman, B.)

APA papers can be tricky to format.

Are you new to APA paper formatting and love videos? Check out Owl Purdue's video on formatting papers here.
*Note: not all college papers require an abstract page. Consult with your professor regarding their preference. 

The core authority on APA paper formatting is the APA Style Manual. You can find a sample paper on page 41 of the Manual. 

If you don't have immediate access to the Manual, check out the sample paper online here via APA Style.

OWL Purdue, also has a great sample paper with clear explanations. It can be found here. 

Headings

Within the body of the paper, it is also important to pay attention to heading levels. Owl Purdue has a great page that talks about headings within your paper. You can check it out here.
