CAS Introduces New Research Services, Recognizes Frequently Requested Articles. (Internet Today)

Article excerpt

Chemical Abstracts Service (CAS) has announced the linking of its early-20th-century records to American Chemical Society's (ACS) Journal Archives, and the release of SciFinder 2002, the latest version of its desktop research tool. CAS also announced the presentation of its Science Spotlight sculptures to those authors and journals whose articles are most frequently requested by researchers.

CAS, ACS Links

Researchers can now use CAS information products to identify journal articles of interest that date to the beginning of the 20th century and then link to the full-text articles in the ACS Journal Archives.

According to the announcement, these two complementary services have been brought together to provide scientists with advanced information retrieval through the availability of a vast electronic collection of original journal literature. CAS completed its Scientific Century project at the end of 2001, making the bibliographic and abstract information from the entire Chemical Abstracts (CA) collection dating to 1907 available for searching through its STN and SciFinder information services. This year, ACS's Publications Division announced the availability of its Journal Archives, which provides access to more than 11,000 ACS journal issues and some 500,000 articles dating to 1879.

CAS users can now identify relevant ACS articles published during the earliest years of CA's coverage, which began in 1907, and complete their exploration by accessing the full-text article using the ChemPort feature included in all CAS and STN electronic services.

SciFinder 2002

Available this fall, SciFinder 2002 will include the following features:

* A new analysis tool for stereochemistry, which can be applied by medicinal chemists who use SciFinder's Substructure Search Module

* Experimental properties for more than 825,000 substances, including both boiling and melting points

* Thousands of reactions from documents dating from 1907-1985. This will bring the total number available through SciFinder to more than 6 million, dating from 1907 to the present.

* New Panorama PreSets, which allow users to more easily define the relationships they wish to explore in scientific databases. …
