The Historical Society’s record keeping system is called PastPerfect. This is an online KEYWORD search database providing researchers the ability to search our records without having to travel to our Headquarters. Library books, vertical files and AV materials are indexed online. Our volunteers are continuing to input records from our extensive document base. Past Perfect also has a link to The Maryland Historical Trust’s information on the state inventoried Harford County properties.
