The Library Catalog tab is the principal means for locating books, journals, and videos in the library's collections. OneSearch can be useful for this purpose at two levels of your research. If you have already identified the book(s) you need through other research methods, search OneSearch Library Catalog by Title or by Author to locate the item(s) in the library. If you are trying to identify books that will be useful for your research, search OneSearch Library Catalog by Keyword or Subject.
