Technical Report Archive & Image Library (TRAIL) is a national collaborative project initiated by the University of Arizona and the Greater Western Library Alliance (GWLA). It is now part of the Global Resources Network of the Center for Research Libraries (CRL), in cooperation with more than 50 partner institutions and personal members.[1][2] TRAIL's purpose is to digitize, preserve, and make openly available technical reports published by agencies of the United States government (initially limited to those before 1975, but expanded in 2015 to remove the date restriction).[3][2] Technical reports often contain detailed information not published elsewhere, but can be difficult to find.[4][5]
From 2012 to 2019, the collection grew from 28,000 to more than 80,000 reports.[6][7] Material is currently available from a number of current and former United States government agencies, including report series from the Atomic Energy Commission, Bureau of Mines, National Bureau of Standards, and National Advisory Committee for Aeronautics.[8]
TRAIL started as a pilot project to digitize, preserve and make accessible a small collection of government agency technical reports, both as proof of concept and to work through technical and logistical issues. The University of Arizona submitted a proposal to Greater Western Library Alliance (GWLA) for a technical report digitization pilot and received funding in early 2006 to begin the project in collaboration with CRL.[9] Led by Maliaca Oxnam of the University of Arizona, the GWLA/CRL Federal Technical Reports Task Force created the appropriate metadata schema, established a pilot search interface at the University of Hawaii and scanned the first complete series, the Monograph Series of the National Bureau of Standards.[10][11]
TRAIL is now part of the Global Resource Network (GRN) within CRL.[12]
The list of digitized series[8] also includes decisions on series not digitized or considered. Decisions are current and subject to future reviews.
Completely digitized series include:
Many other series are in progress, for example:
The search interface[13] is hosted by the University of Washington and searches all TRAIL content found at HathiTrust and UNT.
