Maps of Baltimore City showing block numbers that are used for
organizing references to land transactions recorded by the
Superior Court, 1851-1982, and after that the Circuit Court. The
maps show the block numbers originally assigned in 1886 and the
additional ones after the annexations of 1888 and 1918. Block
numbers remain the same regardless of changes in street names or
house numbers. The block book maps represent the first step in
searching for land records in Baltimore City. They provide the
block number for specific addresses. Researchers then use (Block
Book) in series C2838 and C2839 and (Block Book, New Annex) in
series C2840 to obtain references to (Land Records) in series
C205 and C2482 for all transactions in each block for specified
periods of time.
The maps presented here were maintained by the City Department of Public Works
and comprise the most complete and best preserved set.
Note that the coding on the maps (e.g. 5N5W) represents one square mile
and follows the usage of the Baltimore Topographical Survey.
