Program PrePub Book Link

About PrePub Book Link

PrePub Book Link (PPBL) was modernized to bring together the CIP and PCN Programs into one consolidated system. The entire look and feel of PPBL has been streamlined to be both user-friendly and more attractive. PPBL improves the functionality of the CIP and PCN applications while preserving the mission, which is to provide quality prepublication data to publishers.

Publishers

Authors and Self-publishers

Please use the Author Portal to create a PPBL account and to submit LCCN requests.

Please note: Your old PCN accounts (i.e. peb47528) were not migrated to PrePub Book Link, so you will need to create an account before you can submit LCCN requests.

PCN Publishers

Please use the Publisher Portal to fill out the Application to Participate to create a new account, apply for an upgrade to the CIP Program, and/or to submit LCCN requests.

Please note: Your old PCN accounts (i.e. peb47528) were not migrated to PrePub Book Link, so you will need to create an account before you can submit LCCN requests.

CIP Publishers

Please use the Publisher Portal to submit CIP or LCCN requests.

Please note: If you had a CIP Publisher account in the old system (i.e. caw95843) you may need to activate the old account or create a new account in PPBL. For questions about this, please email cip@loc.gov or use the Contact Us form.
