CSA (formerly Cambridge Scientific Abstracts) was a division of Cambridge Information Group and provider of online databases, based in Bethesda, Maryland before merging with ProQuest of Ann Arbor, Michigan. 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).
