The TRAIL collection contains more than 61,500 federal technical reports, which are searchable and freely available through the TRAIL Search Interface: www.technicalreports.org At an average of 75 pages per report, that's well over 4.5 million pages of content.
TRAIL was formed to meet the challenges of access to U.S. technical report literature. These reports are rapidly disappearing from library shelves and documents collections. TRAIL identifies and digitizes important technical reports, and deposits the resulting files and metadata in trusted repositories: the HathiTrust and the University of North Texas (UNT) digital libraries. TRAIL's work is made possible by its member institutions, which support digitization and cataloging costs through an annual membership fee. The University of California, Los Angeles has recently become TRAIL's newest member. Learn more about TRAIL here.
