Chemical Abstracts Service Launches CAS Science Spotlight

Chemical Abstracts Service (CAS), a division of the American Chemical Society, has announced the release of CAS Science Spotlight, a new Web service that reveals the most highly cited and requested chemistry-related research publications as reflected by the citations included in the CAS databases and the full-text documents requested by scientists through the ChemPort Connection. CAS Science Spotlight will provide not only lists of highly cited and requested documents, but also the bibliographic and abstract information along with the full text (where available)—all free of charge.

CAS Science Spotlight lists the documents most cited for the last 2 publication years in the patents, conference proceedings, Web preprints, and 8,000 journals covered by CAS. The service identifies the scientific papers and chemistry-related patents for which researchers have most frequently requested the full text via the CAS ChemPort Connection, which is available through STN, SciFinder, and SciFinder Scholar. In its initial release, CAS Science Spotlight lists the most requested documents for a 5-week period during the most recent quarter. Future updates will be offered quarterly.

CAS began adding citations to its CAplus database in 1999. According to the announcement, CAS Science Spotlight provides a unique report on citation activity in chemistry research by doing the following:

  • Listing the most frequently cited patent families

  • Providing summaries of concepts and substances covered in the document

  • Presenting links to the electronic full text of the document or to an Adobe PDF copy when electronic full text is not available
"In 1999, CAS began adding citations to our bibliographic database at a rate of nearly 20 million per year," said CAS director Robert J. Massie. "This growing collection of citations is valuable in itself, but even more so in terms of their links within the CAS databases, the world's most valuable compendia of indexed and edited chemical and related information. Science Spotlight is a first step in analyzing this collection and deriving insights into the direction and focus of scientific research today. We thank our colleagues in primary publishing for their cooperation in launching Spotlight, and look forward to working with them and individual researchers to evolve this program in the years to come."

The following publishers, authors, and distributors have provided free full-text documents in Science Spotlight: ACS Publications, Academic Press/IDEAL, American Association for the Advancement of Science (AAAS), American Society for Biochemistry and Molecular Biology (ASBMB), MicroPatent, National Research Council of Canada, Oxford University Press, The National Academy of Sciences of the U.S., Dr. Fredrick Sanger (Cambridge, U.K.), and Dr. Harry Towbin (Basel, Switzerland).

CAS Science Spotlight can be found at or through a link from the CAS home page.
