When in doubt, cite your source

A citation is needed usually when:

  1. You are stating someone else's words, thoughts, or ideas

  2. New information that is considered "uncommon knowledge"

  3. You refer to or use an image, clip, tweet, post, website, etc.

  4. You use your own words, thoughts, or ideas that you have stated in previous work.

A citation is not usually needed when:
