LCCN Registration

Application to the Library of Congress for a Library of Congress Control Number (LCCN) is a fee-based service.

GCG Publishing will apply for an LCCN for your book at your request, with your assistance with regard to the information necessary to fill out the application form. Once the book has been printed, GCG will send a printed copy of your book to the Library of Congress for their consideration.

Please note that the LCCN indicates that the book is being considered for inclusion into the collection housed in the Library of Congress; it does not indicate that the book has been selected. The selection process may be very lengthy due to the number of applicants. The library does not notify the authors that the book has been selected, but selected books will appear in the library’s database when it is updated.

Note: The following are currently ineligible for an LCCN:


-books which do not indicate publication in the United States of America on the title page or copyright page

-previously published books

-books with fewer than 50 pages (genealogies and children’s books are the exception to this rule)
