The online catalog, MnPALS, as well as most of the databases provide 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!
