What type of Integrated Library System (ILS) does the Library of Congress use?
In May 2008, the Library upgraded its ILS to Voyager version 6.5.2 from Ex Libris. A contract for the Library’s first ILS was awarded on May 15, 1998, to Endeavor Information Systems, Inc., for its Voyager integrated library system. On October 1, 1999, the Library successfully completed initial implementation of all modules of the ILS, including cataloging, circulation, acquisitions, serials check-in modules, and the online public access catalog. For further information about the Library’s Integrated Library System, see the Library’s ILS Program Office home page, background page, and FAQ.
