Books, Call Numbers and Shelf Location

Consult the Library Catalog to locate the book's call number . The call number is like the book's
address telling you where to locate a specific book on the shelf--e.g. HF5549.5.I6 S6 2006.

If you are familiar with the Dewey Decimal system, a system which divides knowledge into 10
number categories, our call numbers will look strange to you.

The OSU-Tulsa Library uses the Library of Congress system, a system which divides knowledge
into 21 alphabetical categories.
