Rhode Island Maps
The Rhode Island Historical Society's map collection is very extensive. The Family History Library also has a few maps of Rhode Island, including some of the colonial era and early plantations.
A helpful atlas is Marion I. Wright and Robert J. Sullivan, The Rhode Island Atlas (Providence: Rhode Island Publication Society, 1982; FHL book 974.5 E6w).
Atlases with Rhode Island maps for the years 1790, 1810, 1823, 1838, 1857, 1862, 1878, 1884, and 1917 are on FHL film 002083.
Other printable maps are also available from the National Atlas of the United States -- http://nationalatlas.gov/printable.html
