Research Library

Research Library


The CTR Library contains more than 27,000 unique titles of transportation-related reading and reference materials. Also known as the TxDOT Research Library, we serve as the official repository for the Texas Department of Transportation’s research program. We archive print copies of all of the program’s research publications since 1955 up to the most current research and we provide free online access to all digitized copies in our library catalog.

We strive to collect the most relevant up-to-date material—as well as historic publications—to support TxDOT activities, information dissemination, and knowledge management.

Library services and resources are available to researchers, agencies, students, and the public. Visit our Library Services FAQ page for more information.
