Chemical Abstracts
Chemical Abstracts provides the most in depth indexing and abstracting coverage available of the research literature published internationally in all areas of chemistry, biochemistry, chemical engineering, and related areas. Chemical Abstracts regularly monitors over 9,500 journals, relevant patents from patent offices around the world, conference proceedings, reviews, technical reports, books, dissertations, Web preprints, and more. Complete electronic coverage of this literature extends back to 1907 with growing coverage available for the literature published before 1907. Chemical Abstracts is the most comprehensive index available for identifying research literature in all areas of chemistry.
In its electronic form, Chemical Abstracts is composed of the following two main parts:
CA [PDF]
--covers the literature from 1907-present plus 220,000+ records for pre-1907 journal articles and patents
--updated weekly
--cited references are included for journals, conference proceedings, and basic patents added to the CAS databases from 1997 to the present
--does not contain the full text of the articles, books, and other documents
REGISTRY (REG) [PDF]
--covers the chemical literature from 1907-present, includes tens of millions of sequences from GenBank, plus information from additional databases
--updated daily
--contains records that are created as substances of all types (inorganic and organic) are identified in the chemical research literature and other databases; each substance is given a unique CAS Registry Number which can then be used to identify research publications dealing with that substance through the CA file mentioned above
--contains a wide variety of information about the substances including structure diagrams, alternative name(s), and molecular formulas
The CA and REGISTRY databases (along with MEDLINE) can be accessed via SciFinder Scholar (look for the SciFinder Scholar icon on the desktop of computers running Windows in the Kistle Science Library, the Chemistry Discussion Room, and other locations). SciFinder Scholar is available 24 hours per day.
