Your PIN (or, Personal Identification Number) is is a 4-digit password assigned to your library card and given to you when you first receive your library card.
Your PIN serves as a password to your library account online, and helps protect your privacy.
After logging in to the catalog, you can change your PIN to any 4 to 10 letter / digit combination you desire, by going to My Account / User PIN Change.
If you do not know your PIN, please contact your library to receive a new PIN.
