The Boston Club was established in Greencastle, Putnam County, Indiana, in 1895 to promote education and culture among its members. The collection documents the club's activities from 1899 to 1981 and includes the constitution and by-laws, correspondence, meeting minutes, annual program booklets, newspaper clippings, and an indexed list of names cross-referenced with the program booklets.

The correspondence consists largely of letters requesting donations or offering assistance with the club's various projects. The meeting minutes are loose pages covering only a small number of meetings between 1971 and 1972. The annual program booklets record the club's collect, list each year's officers and committee members, note the meeting schedule and hosts, identify who directed each meeting's program, and list active and associate members. The newspaper clippings document the club's activities as reported in the local newspaper.

The collection is arranged alphabetically.
