Get in the habit of collecting information about your sources as you use them. The library's article databases will supply what you need for your citations, and many of the databases have features for formatting and saving citations as well. The icon for citation information is usually one set of quotation marks.
Citing your sources is an essential part of your work as a member of a scholarly community. Whenever you're unsure about the protocol and can't find a satisfactory answer on your own, chat with a Librarian!
