The St. Louis Mercantile Library has been preserving the art, history and culture of St. Louis and the state of Missouri for 170 years. Our archive, rare book, manuscript and fine art collections encompass all aspects of Midwestern living from the city's founding to the present day.
These collections are complemented by two specialty libraries: the Herman T. Pott National Inland Waterways Library documents the vital role of our nation's rivers as both natural resources and a driving force in America's economic development; and the John W. Barriger III National Railroad Library documents the development of the railroads throughout American history through archives, business records, art and artifacts.
The Mercantile Library features frequent special exhibitions, lectures and artist events that are open to the public, including our annual Fine Print, Rare Book and Paper Arts Fair held the first weekend in May.
Free public tours Saturdays at 11 a.m. and Sundays at 2 p.m. Located at the University of Missouri-St. Louis. Closed major holidays; hours may vary during semester breaks; see the website for current hours.
