One of the finest examples remaining of the work of Philadelphia architect Frank Furness, this was the most innovative library building in the country when it opened in 1891. It was the first library to separate the reading room and the stacks. Peek into the reading room, dominated by a huge fireplace, and with study alcoves lit from skylights above. The unusual exterior stirred controversy when it was built: note the terra-cotta panels, short heavy columns, and gargoyles on the north end.
