From the Center for Research Libraries (CRL):
Fifteen years after the initial pilot, TRAIL consists of over four dozen member institutions whose annual membership fees and volunteered staff time have digitized over 86,000 reports.
In 2006, the Greater Western Library Alliance funded a digitization pilot project to address these issues. In 2007, the pilot project morphed into the Technical Report Archive & Image Library (TRAIL), an ongoing effort that identifies, acquires, catalogs, digitizes and provides unrestricted access to federal agency technical reports.
