Electronic index to certificates of survey and patents, created from a card index, for land in Anne Arundel County. The white cards refer to patented tracts and pink cards refer to unpatented tracts. Entries on the former give name, tract name, current county, patent date, acreage, and citation(s). Entries on the latter give name, tract name, current county, survey date, acreage, and citation. Arranged alphabetically by county where the lands are currently located and then by tract name. The index includes 5,322 entries and provides references to the following Land Office records: (Certificates, Unpatented, AA) in series S1212 and (Patent Record) in series S11. The patent records themselves do not contain plats. This electronic file will serve as the authority file for access to (Certificates, Patented, AA) in series S1189 and (Certificates, Unpatented, AA) in series S1212. The original index cards are available to view in the Archives Searchroom under Index 55.
