Built in 1907, the Romanesque Revival style building is currently a branch of the Nevada County Library System Archived 2010-08-24 at the Wayback Machine.

[8] The building was designed in a Romanesque Revival architectural style by Weeks, the architect of several other Northern California Carnegie libraries.

The seven room, single story plus basement building was constructed by Wilkerson using dark gray man-made stone, plus both rough and smooth concrete blocks, fabricated on location.

Two arched windows are situated in the foyer, the side one being smaller, and the larger front one being of stained glass depicting the lamp of knowledge.

[14][3] There are several signs and plaques on the outside of the building noting the library's various names:[13] Book capacity is 8,000,[8] and the current automation system is Horizon.

[20] Though the Foley was in jeopardy of closing in July 2009 because of county budget cuts,[21] financial support from the Friends of the Library allows it to remain open to the public Thursday, Friday and Saturday 10am-4pm.
