What is I-Share?

The I-Share serves as the online public catalog for 94 CARLI member libraries. I-Share provides participating libraries with an online catalog of their own collection as well as a merged, union catalog of the holdings of all I-Share libraries and supports resource sharing among participating libraries. I-Share also supports library collection management functions including circulation, cataloging, acquisitions, serials control, course reserves and reporting. I-Share runs on the Alma and Primo VE platform from Ex Libris (Part of Clarivate).

Benefits of I-Share Participation


I-Share library patrons may locate and borrow items from other I-Share libraries when those items are not available at their local library. Requested items are sent from the lending library to the borrower's library through ILDS. I-Share’s reciprocal borrowing policy also allows patrons who are registered borrowers at an I-Share library to visit any other I-Share library and borrow items onsite.


The I-Share database contains over 15 million unique bibliographic records and 38.17 million item records, representing the holdings of 94 CARLI I-Share member institutions. The combination of this enormous consortial collection with I-Share’s resource sharing services gives I-Share library patrons ready access to a collection that ranks among the world’s greatest research libraries.


The I-Share Union View and all local library catalogs are all accessible to the public. No login is required to search and view, however a valid ID from an I-Share library is required to borrow items. 


The I-Share community works together with the CARLI staff to provide a wide range of opportunities to learn from each other through best practice documents, educational programming, user forums and topical email lists, training materials, and more. 


CARLI holds a variety of events, primarily online webinars.  Information about upcoming training sessions and events is available from the CARLI calendar, and from the various topical I-Share email lists.
