Library of Congress Control Number
Make your book more accessible to librarians and book vendors by cataloging it with the Library of Congress. When you purchase a Library of Congress Control Number (LCCN) through WestBow Press your book will be numbered and linked to the United States Library of Congress, national libraries, bibliographic utilities and other book vendors so your book is more quickly found. This unique identifier helps people access the correct cataloging data, which the Library of Congress and third parties make available on the Web and through other media.
The LCCN is a serially-based system of numbering and cataloging records. In its most basic form, the number includes the year of registration and a serial number. The year has two digits for 1898 to 2000, and four digits beginning in 2001. The three ambiguous years (1998-2000) are distinguished by the size of the serial number. Some publications are ineligible for a Library of Congress Control Number. Read our FAQ for details.
