Access to materials in all the DePaul libraries is provided through I-Share, the Libraries' online catalog and circulation system. The combined collection of the DePaul University Libraries includes 884,118 print volumes; 277,800 microform volumes; 12,430 current serial subscriptions; 16,675 electronic books; 16,214 electronic serials; over 200 databases; and a diverse audiovisual collection.  The Libraries’ digital image collections are expanding daily to support the priorities set by faculty for classroom instruction and study.  Currently, more than 35,500 images of artistic, geographic or historical interest are available.

In addition to serving as a central catalog for DePaul’s library resources, I-Share also allows users to identify books from 64 other colleges and universities in Illinois, including the University of Illinois. Current DePaul students may choose to borrow directly from these institutions in person or request other libraries’ materials for delivery through the I-Share system. Materials from other libraries across the United States can also be located and obtained through interlibrary loan. Information, brochures, and bibliographies are available at all eight locations and through the libraries’ website. (http://www.lib.depaul.edu/)
