" Mary Foy was only eighteen years old when she was hired to replace Connolly. While it is surprising that such a young person would have been considered for the position, the bigger surprise was that this young person was a woman, since in 1880 the library was still an organization run by, and catering to, men. Women were not yet allowed to have their own library cards and were permitted only in the Ladies’ Room. No library in the country had a female head librarian, and only a quarter of all American library employees were women. The feminization of librarianship was still a decade away. "
