Give as much information as possible, including the State, county,
and town or township; year of interest or range of years; as well as
the type of information you are seeking on the map - for example, streams
and rivers, railroad lines, roads, or cultural features. A researcher will
then be able to determine if any maps in the USGS historical collections
will suit your needs.
To view copies, check with USGS depository map libraries in the state
covered. Also, some may be viewable on the Internet by checking
http://sunsite.berkeley.edu/histopo/,
or http://docs.unh.edu/nhtopos/nhtopos.htm.
General information about historical mapping, including non-USGS
sources of information can be found at:
