It is up to you to locate the elements of a citation from each of your sources.

Four Elements of References Entries:

• Author: who?
• Date: when?
• Title: what?
• Source: where?

Use a period after each type of element. Use commas when separating the parts of an element. Do not put a period after a URL or DOI.
