Books and Manuscripts
The Jane C. Sween Library in Rockville now has over 5,000 books, most of which are partially catalogued at the link above and in the Montgomery County Public Library (MCPL) catalog. The primary focus of this collection is the history of Maryland and the development of Montgomery County from the pre-colonial period to the present including genealogy reference books, biographies, and published Maryland county records. 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 lists of interments (linked above) and published books of collected interment records from various cemeteries in Maryland, Washington, DC, and Virginia. The card index of tombstone readings represents more cemeteries than those linked here.
The Library also retains copies of the 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. For the 2018 updated cemetery inventory data, as well as digitized versions of the 2008 surveys, visit their website hosted at Montgomery Preservation.
