Most of the library databases, EWU Library Catalog, and Google Scholar have built-in citation functions. Look for Cite or a quotation mark icon where the print/email/save functions are.
Note: You still need to know your citation style. Do not trust these computer-generated citations. But they are usually pretty good and you can easily edit the errors.
