APA Citation Guide (APA 7th Edition): Welcome

What is APA Citation Style?

APA Style is a set of guidelines for writing, formatting research papers and assignments, and referencing sources. When citing in APA, you need to cite all the sources that you have used within the body of your work (in-text citation), and in the References List at the end of your essay or assignment. Seneca Libraries citation support and resources are based on the latest edition of the APA Publication Manual (7th edition).
