📖 About Potomac Library
The Potomac Library is the Montgomery County Public Libraries (MCPL) branch serving Potomac and the surrounding communities in the Potomac–Great Falls corridor of western Montgomery County. The branch first opened in 1974 in a rented retail basement, then moved to its purpose-built facility at 10101 Glenolden Drive in 1985. It belongs to a 22-branch countywide system that collectively records over twelve million checkouts a year. MCPL reached its 75th anniversary in 2026, making the Potomac branch one of the system's mid-era facilities. Cardholders can search the statewide MARINA interlibrary loan network, borrow laptops, mobile hotspots and video games, stream films through Kanopy and music through Freegal, and tap Maryland's Sailor statewide database portal — all free with a card.
