Bibliographic Framework Transition Initiative. The Library of Congress is launching a review of the bibliographic framework to better accommodate future needs. A major focus of the initiative will be to determine a transition path for the MARC 21 exchange format in order to reap the benefits of newer technology while preserving a robust data exchange that has supported resource sharing and cataloging cost savings in recent decades.
