Public libraries have a long history of functioning as community centers or public spaces for reading, study and formal and informal public meetings. In 1898, Andrew Carnegie, a prominent library philanthropist, built a library in Homestead, Pennsylvania, where his main steel mills were located. Besides a book collection, it included a bowling alley, an indoor swimming pool, basketball courts and other athletic facilities, a music hall, and numerous meeting rooms for local organizations. It sponsored highly successful semi-pro football and baseball teams. Even before the development of the modern public library, subscription libraries were often used as clubs or gathering places. They served as much for social gossip and the meeting of friends, as coffee shops do today. Throughout history, public libraries were touted as alternatives to dance halls or gentleman's clubs, and frequently built, organized and supported because of their equalizing and civilizing influence.
