The Jane C. Sween Library in Rockville now has over 5,000 books, most of which are catalogued at the link above and in the Montgomery County Public Library (MCPL) catalog.

The state and local histories of Delaware, the District of Columbia, Pennsylvania and Virginia are also strongly represented.
The library holds tombstone inscription readings on index cards from 111 cemeteries and family burying grounds indexed by name (survey done in the 1970s), as well as general survey materials on all known Montgomery County cemeteries, prepared by the Coalition to Protect Maryland Burial Sites working with Peerless Rockville and completed in 2008.
