The Transportation Library and History Center located at the California Department of Transportation (Caltrans) headquarters in Sacramento was established in the late 1940’s as part of the Planning Division. In the early 1970's it was centralized by combining several in-house collections becoming a Department-wide service.

The transportation collection contains approximately 50,000 books, Caltrans technical reports, other state DOT reports and approximately 150 periodical and newsletter titles. The library holds items on all modes of transportation and includes materials on highways and structures design, construction, operations and maintenance, earthquake engineering, transportation economics, taxation, finance and administration, traffic engineering, and environmental planning. Also included is a comprehensive collection from the Transportation Research Board and the U.S. Federal Highway Administration.

Library materials are available in print, CD/DVD and electronic formats.

The History Collection contains materials relating to the Department’s history and its role in California's transportation development and specifically, to its roads and bridges. The collection is comprised of a selection of documents, maps, history files, artifacts, oral histories and photographs from the late 1800’s to the present.
