Two
stories tall, the library is a Neoclassical building with
Palladian influences. Built of yellow brick, it occupies a raised stone
foundation; the
granite details at the top of the foundation sit above the ground. Multiple buttresses are placed on all sides but the rear (west), both supporting the roof and
dividing the walls into segments. Numerous windows are placed mid the buttresses; between the ordinary windows found in most places and the massive
fanlight-topped
stained glass window at the center of the facade, the building has so much glass (all
uninsulated) that it suffers substantial
heat loss because of the fenestration. Even the highest parts of the library are pierced for lighting, as
dormer windows and a
skylight are located in various parts of the roof. Many of the windows are
trimmed with
terracotta, while large stone
risers project from the front on both sides of the stairs. The most prominent part of the building is the entrance on the east front, which is framed by two pairs of columns and crowned with a prominent
pediment. Lesser facades are built on the northern and southern sides, while the western side's exposure to an alleyway has been extensively modified (e.g. the closing of windows) to discourage vandalism and theft. Inside, the library features three floors. Both the basement and first floor are comparable to those of other Carnegie libraries built at the same time: the utility rooms are placed in the basement, along with community meeting facilities, while the first floor centers on the reference/circulation desk and features space for
stacks, adult reading rooms, and children's space. Upstairs, the second floor is occupied by a genealogical library, the Beaver County Research and Resource Center for Local History, and the city's historical museum is located in the basement. Most of the original performance hall in the basement was dismantled in 1961 with the goal of conversion into shelving and reading space, but it was soon renovated as space rented by a state government agency, the
Bureau of Employment Security, before being re-converted for the city museum. Few other major changes have been performed: the second-floor ceiling was lowered to improve heating efficiency, and a small wall was added atop the staircase to prevent people falling down the stairs, but the main floor's high ceilings have remained, and virtually all of the building's original never-painted woodworking survives.
Hand-carven details can be found throughout the building's walnut and oak trim, much of which also features larger components such as
Ionic columns that appear to support the ceilings. ==Preservation==
