Consists of records relating to two major functions of the South Congregational Church of Boston: its sizeable Sunday-school library and the South Friendly Society. The South Friendly Society was a women's charitable organization devoted to supplying indigent female church members with material to make into saleable clothing and to assisting needy people in general. Included in the records are several business letters written by Edward Everett Hale (1822-1909), minister of South Congregational Church from 1856-1909, and by other church officials between 1838-1887, and annual reports by the South Friendly Society. The bulk of the collection, however, is composed of financial records, 1823-1882, including treasurer's accounts, bills listing books purchased for the Sunday-school library, and receipts for sums spent to support charitable causes.
