Visting the Maryland Historical Trust Library as a Historic Preservation Consultant
The Maryland Historical Trust Library is open to historic preservation consultants on Tuesdays, Wednesdays, and Thursdays by appointment only. Please read the information below before scheduling your visit. For further information or to schedule an appointment, contact Karen Golder by email at email@example.com or by phone at (410) 697-9550.
All material relating to Maryland's archeological sites is accessible only to qualified researchers with a valid Medusa account (see below). If you need access to this material, and you do not already have a valid Medusa account, please be sure to allow sufficient time for your account request to be processed.
Medusa, Maryland's Cultural Resource Information System
Through Medusa, you may access information about architectural and archeological 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. Medusa also includes information on resources that have been evaluated for National Register eligibility (Determinations of Eligibility - DOEs).
User accounts are required for access to archeological site data; they are not required for access to architectural records.
Full User Accounts. If you meet the Secretary of the Interior's Professional Qualification Standards for Archeology, you can obtain a "full" account that allows you off-site (remote) as well as in-Library access to the archeological data. Please allow up to two weeks for processing your request.
Proxy Accounts. An archeologist with a valid Medusa account can also request one or more "proxy" accounts for individual co-workers or students who need access to the archeological database for compliance or research projects. Typically proxies are people who work for contract firms or who are students working under a professor's guidance, and who may not meet the Secretary's Standards on their own.
For More Information About Requesting an Account. Please contact Gregory Brown at 410-697-9538 or firstname.lastname@example.org.
Maryland Inventory of Historic Properties
Documentation for the architectural properties on the Maryland Inventory of Historic Properties is maintained for approximately 40,000 architectural resources (individual sites and historic districts). It is suggested that this material be searched using Medusa, Maryland’s Cultural Resource Information System. Several workstations are available in the Library to access this material. You can also view this information off-site at https://mht.maryland.gov/secure/medusa, although you may still need to schedule a visit to view the paper forms, any associated resource reports, and maps of resource locations.
The Architectural Survey Files are kept in binders by MIHP number, and include the full set of data submitted for any particular property. These typically include summary descriptions of the resource, a statement of significance, maps, photographs, negatives, and sometimes drawings. Scanned PDFs of most resources are linked through Medusa, though users should be aware that any recent additions to the paper files may or may not be included in the scanned PDF; the date on which the document was scanned is included on the Medusa record.
GIS Maps are available for MIHP properties on the Library computers using the Medusa Cultural Resource Information System. Available layers include not only the MIHP, but also National Register properties, "short DOE" (determination of NR eligibility) records, and locations of sites in the MHT Easement program. Paper USGS quad maps with marked property locations are also available in the Library.
Architectural Reports are stored in the MHT Library; these include historic structures reports, survey reports, and other more extensive documentation of particular properties. Requests for copying will be granted on an as-needed basis and based on the condition of the material. There is a copying fee.
State Archeological Site Survey
Documentation for the approximately 13,000 archeological properties on the State Site Survey is maintained at the MHT. Again, it is suggested that this material be searched using Medusa, Maryland’s Cultural Resource Information System. Several workstations are available in the Library to access this material.
Note that you will need a valid Medusa account to access this material.
"Full" (non-proxy) Medusa account holders can also view this information off-site at https://mht.maryland.gov/secure/medusa, although you will still need to schedule a visit to view the paper forms, any associated resource reports, and maps of resource location. You may also find useful the MHT Archeological Synthesis Project (http://mht.maryland.gov/archeology_synthesis.shtml).
Archeological Survey Files currently include site-specific survey reports, maps, slides, and documentation for over 13,000 terrestrial and underwater archeological sites ranging from shipwrecks, wharves, piers, aircraft, historic domestic sites, cemeteries, slave quarters, mills, shell middens, and prehistoric villages and camps.
GIS Maps are available for archeological sites on the Library computers using the Medusa Cultural Resource Information System. Available layers include not only archeological sites, but also Phase I survey boundaries and quad files. Physical USGS quad maps with marked property locations are also available in the Library.
Archeology Survey Reports and other more extensive documentation of particular sites are stored in the MHT Library. Copying of these materials is restricted, and responses to requests are decided based on individual situations. There is a fee.
Things to Remember Before Your Visit
Please remember your Medusa password if you are accessing archeological information (you will need it to log on at the Library), and bring a flash drive or something to store your data. Also, you must have your project location clearly marked on a USGS topographic map (not an aerial view).
