To ensure preservation, discoverability, and persistent open access to government technical publications regardless of form or format.
- acquiring content from donor libraries
- arranging for digitization of the materials, including large fold-outs and other special-handling materials
- cataloging/creating metadata for each report
- arranging for storage/preservation of digital files
- creating and maintaining the user interface that provides access to TRAIL digitized content
Government documents that have not been digitized or that are not born-digital are vulnerable for a number of reasons:
- libraries are downsizing print government documents collections due to space issues
- many government documents are deteriorating or are being moved to remote storage
- for many of these documents, access exists only through series records in library catalogs, if at all, while TRAIL individually catalogs each document.
- communicates research in technology and science (prior art)
- contributes to the continued growth of research at institutions and in industry
- serves specialized audiences of researchers (e.g. aerospace, mining, energy, etc.)
TRAIL began as a Greater Western Library Alliance (GWLA) project with the Center for Research Libraries to increase access to and preserve government technical reports. TRAIL is now a CRL Global Resources Network Initiative which provides unrestricted access to this unique body of literature via the TRAIL Search Interface.
Use the TRAIL Search Interface, which is maintained by the University of Washington Libraries.
See the Series List to learn which series have been digitized or the status of a series under review for digitization.
The TRAIL Collections Working Group chooses and prioritizes what series will be added to TRAIL. Any library or other organization may contribute needed content for any active series.
Any interested library may purchase sets of provider-neutral catalog records for available collections via OCLC. These OCLC Record Sets enhance access to existing print collections or electronic versions.
TRAIL content is open for indexing by any/all Internet search engines.
It is a freely searchable database that provides the details about the series that have been received, inventoried, and processed at the University of Arizona, the central processing site for TRAIL.
Individual print documents that are easily scanned (destructive process) are preferred. TRAIL is currently conducting a microform digitization pilot. TRAIL is also developing guidelines, processes, etc. for digitizing maps. Special formats including maps and other non-standard sized items are deposited at the University of North Texas Digital Library
TRAIL has now digitized more than 40,000+ full text U. S. Government technical reports (an estimated 3,417,935 pages!) and more are being acquired, cataloged, and scanned daily.
Users wanting to download TRAIL documents should be aware that only those affiliated with HathiTrust partner institutions can download full PDFs. Users not affiliated with HathiTrust partner institutions can download TRAIL documents, page by page. For more information see Can I download a whole book? on the HathiTrust Help page.
Dozens of academic, government, and commercial organizations have contributed content, services, funding, and staff time to TRAIL and members invest in these efforts to keep it going and growing.
