A new web service from Chemical Abstracts Service (CAS),
a division of the American Chemical Society, 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.
Most Cited Journal Articles, Journals and Patent Families in CAS databases 1999-2000
CAS Science Spotlight lists the documents most cited, for the last two publication years, in the
patents, conference proceedings, Web preprints or one of the 8,000 journals covered by CAS,
producer of the world's largest collection of scientific information.
Most Requested Documents of the Quarter
CAS Science Spotlight identifies the scientific papers and chemistry-related patents for which
researchers have most frequently requested the full text via the CAS ChemPort Connection, available
through STN, SciFinder and SciFinder Scholar. In its initial release Spotlight lists the Most Requested
documents for a five-week period during the most recent quarter. Future updates will be offered
quarterly.
CAS began adding citations to its CAplus database in 1999. Science Spotlight provides a unique
report on citation activity in
chemistry research by:
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 a 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."
