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.
Frequently Asked Questions
No, not at present. The TRAIL Search Interface does not have a "browse" function because a large share of TRAIL content consists of documents for which agency names and series titles have changed frequently over the years. Creating and maintaining an authority record structure, which would pull together all the variant combinations for each agency/series pairing, would require a significant investment of our resources at this time.
Some digitized reports may not be available due to copyright restrictions. TRAIL content in the HathiTrust is subject to copyright decisions made by HathiTrust. For more information about copyright see the HathiTrust copyright page.
Anyone can download TRAIL documents, page by page. HathiTrust partner institutions can download documents page by page or can download a PDF of the complete document. The complete document is available for viewing online. For more information see Can I download a whole book? on the HathiTrust Help page.
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.
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
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.
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 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.
- 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.)
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.
- 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
No. Any of the following will benefit TRAIL: membership dollars, service on TRAIL working groups, educating others about TRAIL, donation of materials.
- TRAIL Collections Working Group
- TRAIL Communications Working Group
- TRAIL Processing Working Group
- TRAIL Membership Working Group (new!)
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.
