Our Research Facility contains archives, court records, genealogy materials, photographs and much more.

Until further notice, our research facility is open Wednesday, 10am – 2pm, by appointment only.

There is a $5 fee for non-members to conduct research in the facility.

The Archives

contain more than 250,000 original source items dating back to the 1600s. These include plats, deeds, letters, diaries, scrapbooks, ledgers, documents, maps, postcards, newspapers, and legal and business correspondence. Attendants are available to assist researchers.

Court Records

are available at Harford County’s courts. Records begin about 1774 when Harford County came into existence. Cataloging has proceeded up to about the mid 19th century. The materials are being cataloged and indexed by volunteers for use by researchers. Volunteers hope to eventually have all of the records computerized to assist researchers in finding material for future projects. The records provide background on everything from criminal charges to land transactions, bastardy cases, indentures and emancipation of slaves and servants and more.
