APA Style & Citation 7th edition

How to format your paper and cite your sources using 7th ed. APA style.


If you are on a large website with multiple web pages, your citation should include the full URL (address) to the page you used, not only the home page.

For the publication date, use the one that corresponds to the page you are referencing (not the copyright date for the entire site). Last updated date is ok but last reviewed is not. If there is no date use n.d.

If the information is expected to change, include the retrieval date before the url. Otherwise include only the URL.

Author's last name, initials. (date of publication). Title of document.  Site name if different from author. Retrieved date, from http://Web address
