UMSL operates three campus libraries: the Thomas Jefferson Library, St. Louis Mercantile Library and Ward E. Barnes Library. Combined holdings include more than 1 million volumes, 1.3 million government documents, 1.2 million microforms, nearly 3,000 serial titles and access to more than 14,000 electronic journals.
Thomas Jefferson Library: As the prices of library journal subscriptions rise, libraries across the country are forced to cut back. Technology continues to advance, and the Thomas Jefferson Library strives to provide these resources. Financial support is an important component in accomplishing these initiatives.
St. LouisMercantile Library: The St. Louis Mercantile Library opened in 1846 and is the oldest cultural institution in continuous operation in St. Louis. The Mercantile also is a museum, with a variety of exhibits on display throughout the year. This library contains two unique collections:
Herman T. Pott National Inland Waterways Library: This 15,000 volume collection focuses on America's inland rivers and some coastal waters both as natural resources and as developed waterways for transportation.
John W. Barriger III National Railroad Library: The Barriger Railroad Library includes over 45,000 volumes covering all aspects of railroading, and dates from the beginnings of railroads in the 1820s to the present day.
