Writing in theday.com, a Connecticut web site, David Collins warns that the Indian & Colonial Research Center in Old Mystic, Connecticut, is in danger of closing. Funds and volunteers are both hard to find these days.
Built around the original papers and works of the late Eva Lutz Butler, the collection is as interesting as it is varied, from an impressive collection of local arrowheads, some many thousands of years old, to a genealogical library so complete it's been established as a Connecticut Registered Genealogical Research Center.
There are also rich catalogues of historic photographs, thorough land records and maps for local towns, examples of pottery and baskets made by the region's American Indians, and even a cannonball from the Battle of Stonington.
