The physical card catalog of old can be found in its digital format at https://bcfls.tlcdelivers.com/#section=home. Use this site to search for materials to borrow, put them on hold if not available at the moment, renew already checked out materials, and manage your personal library account.
But that’s not all! There is an online catalog for the kiddos. This can be found at https://bcfls.tlcdelivers.com/kids#/categories. More or less, this is a graphics-based version of the aforementioned online catalog.
