Anyone can browse our online catalog at https://catalog.maryslibrary.com

We’re partnering with a consortium of PA libraries called SPARK to offer a modern, open-source catalog that connects us to other libraries across the state, while also making for a more convenient and immersive patron experience. In September 2026, SPARK switched its service to Aspen Discovery.
To access our online catalog, you must be an existing library patron with either a physical card or an online digital account. If you are already signed up for an account, you do not need to reregister with Aspen.
For information on how to use our online catalog, see the Aspen Discovery FAQ (online as a PDF).
