==History==
पंक्ति 7:
Although most of the bibliographic information is now electronically created, stored and shared with other libraries, there is still a need to identify each unique record, and the LCCN continues to perform that function.
[[Librarian]]s all over the world use this unique [[identifier]] in the process of cataloging most books which have been published in the United States.
In February 2008, the Library of Congress created the LCCN Permalink service, providing a stable URL for all Library of Congress Control Numbers.<ref>{{cite web |title=Library of Congress Update for 2008 ALA Annual Conference: January–May, 2008 |url= http://www.loc.gov/ala/an-2008-update.html |accessdate=2008-09-29}}</ref>
