How do I find out what Penn State owns?
The CAT, short for catalog, contains information on the over 5 million books, journals, documents, videos, music and more owned by the Libraries. The CAT does NOT provide a listing of journal articles -- for that you should use LionSearch. For more information about using The CAT, consult the Quick Guide to the CAT. For more information about using LionSearch, consult the LionSearch FAQ.
Tip #1: Use the I WANT IT button in the CAT to have things delivered for pickup or to request an item already in use.
Tip #2: My Library Account shows you what you have checked out and allows you to renew your books without coming to the library. You can borrow up to 200 items; most items can be charged out until the end of the current semester before needing to be renewed.
How do I find items on the shelf?
The Penn State libraries use the Library of Congress call number system to shelve most items in the libraries. Below are two examples of this call number system.
