In 1927 Susan Butler opened a free library and reading room in Dart Hall, using her father’s books, folding chairs, and two tables. The reading room was open Mondays, Wednesdays, and Fridays from 5:00 to 8:00 p.m. Dart served as librarian and operated the room with donations and at her own expense until the Charleston Free Library established the Dart Hall Branch in 1931. The Charleston County Free Library and its branches received money from the Rosenwald Fund and the Carnegie Foundation, while the Dart family rented the building to the county for one dollar a year. The Dart Hall Branch opened to the African American public with 3,600 books.
