Warder Public Library is a historically significant building in Springfield, Ohio, United States.

A robust example of Richardsonian Romanesque architecture, it was a gift to the city from industrialist Benjamin H. Warder, and served as the main branch of the Clark County Public Library from 1890 to 1989.

Richardson died in 1886, but architects in his office completed the houses and formed a successor firm: Shepley, Rutan and Coolidge.

[3] In plan and massing, the building is closely related to Richardson's Converse Memorial Library (1885) in Malden, Massachusetts.

[This quote needs a citation] In 1989, the Clark County Public Library moved to a modern facility at 201 South Fountain Avenue.
