Conference paper


An integrated private database on STN International has been designed and implemented by Du Pont and Chemical Abstracts Service (CAS). The database, named SCION, consists of a chemical file and a document file. A unique feature of this system is that both Du Pont proprietary files and publicly available files on STN International can be searched using the same MESSENGER command language. The chemical file contains structures, Du Pont accession numbers (called C-Numbers), molecular formulae, systematic names, synonyms, descriptors, and CAS Registry Numbers (for equivalent organic, inorganic, and polymeric substances). The document file comprises bibliographic data, abstracts, subject indexing via controlled vocabulary terms, and an online hierarchical thesaurus of these controlled terms. Custom features, system capabilities, and preliminary reactions of users to the online database are discussed.
