Letters APA

American Psychological Association, or APA, format is a style of crediting sources you use to write a paper. This style is typically used for research papers with medical or scientific subject matter.  

Use our APA Citation Guide  to learn how to cite sources in this style.

Every time you quote or paraphrase someone else’s work, you must indicate:

  • who wrote the work
  • what is it called
  • and where we (the reader) can find a copy.

You give us this information in two places:

  1. In the paragraph where you are quoting or paraphrasing. This is called a Parenthetical Citation because you will put brief information about the work in parentheses. 
  2. In the References page at the end of the paper. This is where you put all of the information we need to find a copy of the works you used in your paper.
