You can use the BiblioCommons catalog, the Classic Catalog, and SFPL website without logging in. To access your library account online, you must login to BiblioCommons or to the Classic Catalog.
To sync BiblioCommons features with your existing Library Card account, there is a one-time registration using your existing Library Card number (barcode) and PIN (password). The good news is, once you register, you can use your username OR barcode to log in to BiblioCommons -- you don't need to enter your 14-digit library card number.
