Information Needs

Library Catalog and Renewals

The collection is listed in a computerized catalog. You may access the catalog with CyberMARS Computers located in every library, or with your library card through the library's web page using the Catalog & Databases tab. With Catalog & Databases you can also:

  • View your borrowing record and recheck borrowed items
  • Place materials on reserve
  • Search library databases

    E-Notify is a library service that allows you to have notifications for reserved materials ready for pick-up and overdue materials sent to your e-mail address rather than receiving them through the postal service. On reserve pick-up, you must confirm that you have received the e-mail within 24 hours or you will still receive the paper notice through the mail.
