In-text citations - a short, unique entry included in the body of your paper for a source you used. It allows readers to identify the full entry on the References page.
References page - an alphabetical list of all the sources you used in your paper (not the ones you looked at, just the ones you mentioned in your paper) with enough information so the readers could find the source themselves.
Rule: All sources on the References page must be cited in-text and all in-text citations must have a corresponding References entry (with the exception of personal communication and classical works, which are only cited in-text).
