You will want to follow your instructor's expectations when choosing which citation format to use. The SMSU Library's Citation help link provides recommended resources to use as well as tools that can help you create citations.
OneSearch as well as most of the databases provides shortcuts to citations. When you identify a book or article you'll likely use in your paper or speech, look for a shortcut to the citation for that resource. It's usually there...and it can be a great time saver!
Note that the citations are not always 100% correct, but they are a good starting point and have the basic information you need to create a citation. Usually the errors have to do with capitalization, italics/underlining, or punctuation. Double-check them!
We have print copies of these major citation formats at the Reference Desk. These copies are for in-house use only (although we do have one circulating copy as well as older editions that are available for checkout).
