APA references
The basics:
APA references generally include information about the author, publication date, title, and source. Depending on the type of source, you may have to include extra information that helps your reader locate the source.
Reference examples
Citing a source starts with choosing the correct reference format. Pay close attention to punctuation, capitalization, and italicization.
Missing information
It is not uncommon for certain information to be unknown or missing, especially with sources found online. In these cases, the reference is slightly adjusted.

Formatting the APA reference page
The basics
On the reference page, you list all the sources that you’ve cited throughout your paper. Place the page, right after the main body and before any appendices.
On the first line of the page, write the section label “References” (in bold and centered). On the second line, start listing your references in alphabetical order.
Apply these formatting guidelines to the APA reference page:
- Double spacing (within and between references)
- Hanging indent of ½ inch
- Legible font (e.g. Times New Roman 12 or Arial 11)
- Page number in the top right header
Which sources to include?
On the reference page, you only include sources that you have cited in the text (with an in-text citation). You should not include references to personal communications that your reader can’t access (e.g. emails, phone conversations or private online material).
