Contrails' focus is on United States Air Force technical reports from 1949 through the 1980s, which are much less consistently available online when compared to those issued by the National Aeronautics and Space Administration (NASA) and its predecessor, the National Advisory Committee on Aeronautics (NACA). The bulk of the Contrails' digital collection consists of pdf files of published technical reports scanned from paper originals.
The Contrails database can be searched by title, author, laboratory, or any of the identification numbers assigned to a report (e.g., AD number, Task number, etc.).
U.S. Defense Technical Information Center's gateway to unclassified technical reports and specifications. Formerly DITC Public STINET.
U.S. Defense Technical Information Center's technical reports and specifications, mostly in fields related to aerospace engineering and aerodynamics. STINET MultiSearch allows simultaneous searching of up to 34 databases including NASA, NIH, DOE, EPA, FDA, and USDA.
Administered by the US Department of Commerce, NTIS is the Federal Government's clearinghouse for scientific, technical information produced by or for Federal agencies.
The database 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: Citations and reports from the National Advisory Committee for Aeronautics period lasting from 1915 to 1958, with information dating back to 1900.
• NASA Collection: Citations and documents created or sponsored by NASA starting in 1958 and continuing to the present.
• NIX Collection: Citations and links to the images, photos and movies once contained in the NASA Image eXchange as well as other collections currently curated by NASA and its various centers.
SciTech Connect makes available over 70 years of research results from DOE and its predecessor agencies. Research results include journal articles and related metadata; technical reports; scientific research datasets and collections; scientific software; patents; conference and workshop papers; books and theses; and multimedia.
SciTech Connect contains nearly 3 million citations, including citations to 1.5 million journal articles, 1 million of which have digital object identifiers (DOIs) linking to full-text articles on publishers' websites. It also has more than 445,000 full-text DOE-funded STI documents.
The Technical Report Archive & Image Library (TRAIL) identifies, acquires, catalogs, digitizes and provides unrestricted access to U.S. government agency technical reports. TRAIL currently consists of over three dozen member institutions whose annual membership fees and volunteered staff time further the efforts of the project.
WorldWideScience.org is a global science gateway comprised of national and international scientific databases and portals. WorldWideScience.org accelerates scientific discovery and progress by providing one-stop searching of databases from around the world. Multilingual WorldWideScience.org provides real-time searching and translation of globally-dispersed multilingual scientific literature.
Currently, approximately 100 databases and portals from over 70 countries are searchable through WorldWideScience.org. Users get the most current findings in fields such as energy, medicine, agriculture, environment, and basic sciences, including access to scientific and numeric data sources. Much of the information accessed via this gateway is freely available and public domain.
