How to cite a Wikipedia article
Quick answer
Always cite a specific revision via the permanent URL (History → Permalink), never the live URL.
Why this one is tricky
Wikipedia articles change constantly and any reader can edit them.
Example (APA 7)
Citation. (2024, April 2). In Wikipedia. Retrieved from https://en.wikipedia.org/w/index.php?title=Citation&oldid=EXAMPLE
Official source
APA 7 is defined and maintained by the American Psychological Association. For edge cases their official guidance is the authoritative reference — DEEPNOTIS follows the same canonical APA 7 definition.
Most common mistake
Using Wikipedia as a primary source. It's a tertiary reference — cite the primary sources Wikipedia links to instead.
Citing a Wikipedia article more than once?
