NASA Technical Report Server
Provides access to aerospace-related citations, full-text online documents, images, and videos. The types of information included are: conference papers, journal articles, meeting papers, patents, research reports, images, movies, and technical videos – scientific and technical information (STI) created or funded by NASA. The NTRS integrates the following three NASA collections and enables search and retrieval through a common interface: NACA Collection includes citations and reports from the National Advisory Committee for Aeronautics lasting from 1915 to 1958 with information dating back to 1900, the NASA Collection includes citations and documents created or sponsored by NASA in 1958 and continuing to the present, and non-NASA materials including historical metadata records of related research topics collected from a variety of non-NASA sources that are of interest to NASA researchers.
