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.

Digitized technical reports are located in HathiTrust and in the University of North Texas Digital Library.

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
