During the Centennial Exposition in Philadelphia in 1876, 103 librarians, 90 men and 13 women, responded to a call for a "Convention of Librarians" to be held October 4-6 at the Historical Society of Pennsylvania. At the end of the meeting, according to Ed Holley in his essay "ALA at 100," "the register was passed around for all to sign who wished to become charter members," making October 6, 1876 the birthday of the American Library Association.
