The Maryland Historical Trust is proud to introduce Medusa, the State of Maryland's Cultural Resource Information System. Through Medusa, qualified resource professionals are able to access information about resources recorded in the Maryland Inventory of Historic Properties (MIHP) and the National Register of Historic Places (NRHP), as well as properties on which MHT holds preservation easements and information on resources that have been evaluated for National Register eligibility (Determinations of Eligibility, or DOEs). The system will allow access to archaeological records to professional archaeologists, agency representatives, and researchers working directly with professional archaeologists.
Limited use of the database is available to the public. It consists of a searchable database that is linked to Maryland Archaeological Site Survey files, synopsis reports, and cover sheets generated of excavation projects.
The database features the text, map coordinates, and more for each marker, as well as thematic tours and story maps.

Historic Building Preservation, Rehabilitation, and Restoration Resources at the Maryland Historical Trust Library
The MHT library holds approximately 5,000 books and journals, as well as reports and gray literature on a wide variety of archaeological and architectural and historic preservation related studies. The collection also contains unique material related to architectural and archaeological research completed by MHT. Highlights include:
Maryland Inventory of Historic Properties
Documentation for the architectural and archaeology sites which make up the Maryland Inventory of Historic Properties is maintained for approximately 43,000 architectural resources (individual sites and historic districts) and more than 13,000 archaeological sites (prehistoric and historic). The architectural portion of the inventory is accessible to the public; however, archaeological research files are restricted to use by qualified professionals.
Architectural Survey Files typically include summary descriptions of the resource, a statement of significance, maps, photographs, negatives, and sometimes drawings. Survey files can include documentation about structures as varied as "houses" of all sizes and types (big houses, little houses, brick houses, frame houses, lighthouses, school houses, smoke houses, slave houses), towers (water towers, fire towers, bell towers), privies, barns, corn cribs, churches, railroads, bridges, milestones, industrial buildings, and a B-29 bomber.
Archaeological Survey Files currently include site-specific survey reports, maps, slides, and documentation for over 13,000 terrestrial and underwater archaeological sites ranging from shipwrecks, wharves, piers, aircraft, historic domestic sites, cemeteries, slave quarters, mills, shell middens, and prehistoric villages and camps. Access to all archaeological documentation is restricted to qualified researchers who have been approved by MHT archaeological staff.
The vertical file collection at the MHT library contains a wealth of information related to historic buildings and properties from across the state. These files include material which complements reports completed for the Maryland Inventory of Historic Properties and National Register of Historic Places, including architectural drawings, newspaper clippings from national, state, and local newspapers, photographs, notes, and ephemera.
MHT library holds a small collection of drawings of structures listed the Maryland Inventory of Historic Properties and National Register of Historic Places.
Slides & Photographs
The library holds an extensive collection of slides and photographs of historic properties. Many of these photographs were taken as documentation for admission to MIHP and NRHP and generally date from the 1960s to present. The collection often supplements images in included in the scanned MIHP form found online through Medusa. The collection is currently being inventoried.
