If you know the source you want to use, search for it by title in the library catalog (in the case of a book) or by starting with the journals list at the library website (to find the full text of an article in an e-journals collection or database). Alternatively, e-mail the citation to email@example.com so that I may find the full text for you.
If you do not know the source you want to use, search for possibilities in the library catalog (especially to locate books) and the research databases (especially to locate articles). See the next section for details. In addition, you are welcome to e-mail firstname.lastname@example.org with the name of the theologian and a request for help.
