Once you are in iBistro (the catalog), click on My Account in the darker blue bar.
Click on User PIN Change.
Enter your library card number in the Card No. box.
(If the barcode begins with a "D", change the "D" to a "2").
Enter your current PIN.
(If you are using your card for the first time or are having problems with your PIN, CHANGEME is probably your PIN.)
Enter a new PIN in the Enter new Pin box. (Your PIN should be at least 4 characters and no more than 10 characters long; it can be uppercase letters or a combination of uppercase letters and numbers.)
Verify your new PIN by entering it again in the Re-enter new PIN box.
