What is a library catalog?

A library catalog is a database of materials held by the library. You can use it to find books, journals, and DVDs (and some other formats) in the library's collection.

Looking for an article? Use Summon, or select and search one of the research databases.

Search the library catalog by author, title, subject, journal title, and call number. Some materials may be renewed online. Help screens are available for most functions. Please tell a library staff member about any inaccuracies or discrepancies.

Call numbers

Most of the printed materials in the library are shelved by Library of Congress call number. Library of Congress call numbers give each book a unique identifier, assuring it a particular place on the shelves. Call numbers also help group items by subject.
