Now Available. The Next Generation NTRL V3.0

The NTRL V3.0, developed by the Federal Science Repository Service (FSRS) is based on the open-source data-management framework Fedora/SOLR. This new platform offers significant advantages with highlights including enhanced searching, comprehensive results display, support of multiple date-types including reports, images, videos, and more. NTRL V3.0 subscribers will enjoy a robust, content-driven environment for accessing the NTIS collection.

Recently AddedOver 195K thin meta-data records of pre-1964 information. This retrospective conversion of paper-formatted catalog cards to digital meta-data, on a variety of subjects, represents the culmination of a significant investment of resources by NTIS to enhance the value of the content collection of the NTRL V3.0. Although NTIS does not offer full-text availability for many of these meta-data records, in the interest of providing our subscribers greater potential of discoverability, they have been integrated among the existing NTRL V3.0 content.
