Process
Publishers who would like to participate in the PCN Program must first apply for a PCN Publisher Account in PrePub Book Link. Once the publisher account has been approved, publishers can begin submitting LCCN requests. Publishing houses with multiple imprints should create an account for each imprint.
Authors can submit an LCCN request after creating an account in PrePub Book Link, without waiting for approval by Library staff.
Based on the information provided by the author or publisher, Library staff assign a preassigned Library of Congress Control Number (LCCN) to each title. The publisher or author prints the LCCN on the back of the title page (i.e., the copyright page) in the following manner:
Library of Congress Control Number: 2019012345
