University of California Digital Library: “The National Technical Reports Library (NTRL – U.S. Department of Commerce) has become an open access resource, following a decision made by the National Technical Information Service (NTIS). NTRL was previously licensed as Tier 2 by five UC campuses. With the change of NTRL to open access, the PID redirects to the Open NTRL platform and a catalog record for Open NTRL will be available soon.
