*Online access to the library catalog is provided through the Voyager system from
ExLibris Inc. Public terminals for the Online Public Access Catalog (OPAC) are located
in the lobby and at various locations in the Library. The library catalog can also be
accessed online. Search by author, title, subject, journal title, and call number. Some
materials may be renewed online. Help screens are available to assist in understanding
most functions. With few exceptions, the catalog contains full information on the
libraries’ holdings. Patrons are urged to bring inaccuracies or discrepancies to the
attention of a member of the staff.
Virtually all of the printed materials in the libraries are shelved by Library of Congress call number. Library of Congress call
numbers not only provide a unique identifier for each book, assuring it a particular
place on the shelves, but also reflect an effort to order the collection by subject
matter. Learn more
