Cambridge Scientific Abstracts (later simply CSA) was a division of Cambridge Information Group and provider of online databases, based in Bethesda, Maryland, before merging with ProQuest of Ann Arbor, Michigan, in 2007. CSA hosted databases of abstracts and developed taxonomic indexing of scholarly articles. These databases were hosted on the CSA Illumina platform and were available alongside add-on products like CSA Illustrata (deep-indexing of tables and figures). The company produced numerous bibliographic databases in different fields of the arts and humanities, natural and social sciences, and technology. Thus, coverage included materials science, environmental sciences and pollution management, biological sciences, aquatic sciences and fisheries, biotechnology, engineering, computer science, sociology, linguistics, and other areas.

Aerospace & High Technology Database

The Aerospace and High Technology Database is a bibliographic database covering the space sciences as well as aeronautics and astronautics. This database also provides access to complementary disciplines, such as electronics, chemistry, physics, geoscience, and communications. The print equivalent is International Aerospace Abstracts (IAA) and Scientific and Technical Aerospace Reports (STAR from 1986 to 1993).

The Aerospace & High Technology Database began as two print publications, International Aerospace Abstracs (IAA) and Scientific and Technical Reports (STAR) Index. These were then incorporated into the Aerospace Database, produced by the American Institute of Aeronautics and Astronautics.

International Aerospace Abstracts

International Aerospace Abstracts was published by the Technical Information Service of the American Institute of Aeronautics and Astronautics, with an ISSN 0020-5842. Other previous authors was National Aeronautics and Space Administration (NASA) and the Institute of the Aerospace Sciences. It was published alternately with the Scientific and Technical Aerospace Reports in 1963. International Aerospace Abstracts was part of the International Aeronautical Abstracts section of the publication entitled Aerospace Engineering (ISSN 0096-669X).

Scientific and Technical Aerospace Reports

According to the NASA website: Effective May 2011, Scientific and Technical Aerospace Reports (STAR) is being retired, along with several other NASA scientific and technical information products.

Scientific and Technical Aerospace Reports (STAR) is an information resource listing citations and abstracts of NASA and worldwide aerospace-related scientific and technical information (STI). Updated biweekly, STAR highlights the most recent additions to the NASA Aeronautics and Space Database. Through this resource, the NASA STI Program provides timely access to the most current aerospace-related research and development (R&D) results.

STAR subject coverage includes all aspects of aeronautics and space research and development, supporting basic and applied research, and application, as well as aerospace aspects of Earth resources, energy development, conservation, oceanography, environmental protection, urban transportation and other topics of high national priority. The listing is arranged first by 11 broad subject divisions, then within these divisions by 76 subject categories and includes two indexes: subject and author.

ISMEC Bulletin was published by Cambridge Scientific Abstracts. Now, Mechanical Engineering Abstracts is also known as "ISMEC, Mechanical Engineering Abstracts". Another title is "Information service in Mechanical Engineering Bulletin".

Temporal coverage for Mechanical Engineering Abstracts is from 1981 to 2002. Current information, beyond its temporal coverage, is not part of this database. Current information is located in Mechanical & Transportation Engineering Abstracts (see next section below). As of May 2010, this database contained more than 215,700 records.
