📖 About Rockville Memorial Library
Rockville Memorial Library is the main branch of Montgomery County Public Libraries (MCPL), serving the county seat from the heart of the Rockville Town Square district. The library grew out of Rockville's earlier downtown branch on Maryland Avenue and moved into its current landmark building, designed by the firm Grimm + Parker, in November 2006. The architecture is a deliberate homage to the nearby genomics research corridor and the Human Genome Project: sweeping curved exterior walls, double-helix patterns in the first-floor tilework and bookcases, and murals tracing the history of the city. Owned and operated by Montgomery County, the branch is part of the countywide MCPL system, so a single library card borrows across every Montgomery County branch and connects to Maryland's statewide Sailor network. Today it pairs a large browsing collection with meeting and collaboration spaces, public technology, and a full slate of programs for children, teens and adults just steps from the Rockville Metro and Ride On bus routes.
