Donations of artifacts, papers and other materials that are locally historic or relate to the historical development of Castleton are welcomed. Written materials like diaries, letters, articles, and photographs are especially appreciated. The acceptance of donations of larger artifacts is contingent upon the approval of the Museum Committee because of severe space limitations. The Castleton Historical Society considers all gifts to be unrestricted and without limiting conditions. All donations are tax deductible; however, the museum is staffed by volunteers and cannot take responsibility for assessing the value of donations.
