The American Revolution and Its Era: Maps and Charts of North America and
the West Indies, 1750-1789 represents an important historical record of
the mapping of North America and the Caribbean.
Most of the items presented here are documented in Maps and Charts of
North America and the West Indies, 1750-1789: A Guide to the Collections
in the Library of Congress compiled by John R. Sellers and Patricia Molen
van Ee in 1981. The bibliography contains approximately 2,000 maps and
charts. Over the next several years many of the maps and charts in this
bibliography will be added to the online collection each month.
The collection is called Revolution Era Maps 1750-1789.
If you find any that are of particular interest please post their titles
