Medusa, Maryland's Cultural Resource Information System

Request User Account

IMPORTANT NOTE: User accounts are required for access to archaeological 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 receive a "full" account that allows you off-site (remote) as well as in-Library access to the archaeological data. Submit an account request at the link below. You will be asked to agree to the Terms and Conditions and then fill out a form with your contact information along with a brief description of your qualifications and purpose. Once you submit the request and your account has been activated, you will be contacted by email with your account details and password. Please allow up to two weeks for processing your request.


If you believe you would not qualify for a "full" account but still need access to the archaeological data, have your supervising archaeologist request a "proxy" account for you (see below).

"Proxy" Accounts

An archaeologist with a valid Medusa account can also request one or more "proxy" accounts for individual co-workers or students who need access to the archaeological 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. The "sponsoring" archaeologist can submit a proxy request by logging into their account, selecting Manage Account in the upper right, and clicking on their company in the Affiliation box. At the bottom of the Company Information screen there will be an "Add a Proxy User" button. Note that the requesting archaeologist will need the proxy's name and email address, and will need to agree to hold the proxy responsible to the same Terms and Conditions regarding disclosure of site location.

Once the request is submitted and the proxy account has been activated by MHT staff, the proxy will be contacted by email with his or her account details and password. Again, please allow up to two weeks for processing your request. Normally proxies do not have remote access to Medusa, but will be able to use the system at the MHT Library.

Once You Have Your Confirmation Email

After you get an email with your user name (the email address you registered under) and password, you may start using the system. If you have a "full" account, you can enter Medusa from any computer and click on the Log In button in the upper right. For proxy or other in-Library use of Medusa, please email or call Lara Westwood (, 410-697-9546) to schedule an appointment. The library is open to the public on Tuesdays, Wednesdays, and Thursdays. Please remember your password (you will need it to log on at the Library) and bring a flash drive or something to store your data.
