PCN Process


Please note that this is a two-step process. All publishers wanting to participate in the PCN Program must first complete and submit an Application to Participate. When the application has been approved, an account number and password will be sent to the publisher via email. Then, publishers participating in the program logon to the PCN system and complete a Preassigned Control Number Application Form for each title for which a preassigned control number is requested. Based on the information provided by the publisher, Library staff preassign a control number to each eligible title. Upon receiving the number, the publisher prints it on the back of the title page (i.e., the copyright page) in the following manner:
