I have a statewide MPower card. May I use it in Prince George’s County?
The statewide MPower card is valid in Prince George’s County libraries. Before your first use of the MPower card, you must present it in a Prince George’s County Memorial Library System (PGCMLS) branch. You will be asked to present ID and fill out an application. You will need a PGCMLS library card number to access some databases offered by PGCMLS.
