The library's Online Public Access Catalog (OPAC) is a computerized catalog similar in some respects to a card catalog but far more advanced in the search facility it offers library users. These include keyword searches in the title, subject and name files. The same bibliographic information is included. The OPAC comprises all library holdings. Periodicals are also recorded in a computer print-out catalog. Any item in the library can be searched through the OPAC by author, title, subject and call number.
