  3. 3. Organization of the Print CAS <ul><li>80 sections divided among </li></ul><ul><ul><li>Biochemistry </li></ul></ul><ul><ul><li>Organic </li></ul></ul><ul><ul><li>Macromolecular </li></ul></ul><ul><ul><li>Applied </li></ul></ul><ul><ul><li>Physical, Inorganic and Analytical </li></ul></ul><ul><li>See http://www.cas.org/products/print/secgr/index.html for more details </li></ul>
  4. 4. Volume Indexes <ul><li>Author </li></ul><ul><li>Patent </li></ul><ul><li>General Subject </li></ul><ul><li>Chemical Substance </li></ul><ul><li>Formula </li></ul><ul><li>http://www.cas.org/products/print/ca/volindex.html for more information </li></ul>
  5. 5. STN International (Online version of CAS) <ul><li>Allows Access to hundreds of scientific, technical and medical databases including CAS ( List of databases ) </li></ul><ul><li>Pay as you go. Pricing is based on time online and information retrieved </li></ul><ul><li>Suited for experienced searchers </li></ul><ul><li>STN Easy version for infrequent searchers </li></ul>
  6. 6. Searching CAS on STN <ul><li>Based on Boolean logic </li></ul><ul><li>Can search on many fields as shown in the CA database summary sheet </li></ul><ul><li>STN Easy </li></ul><ul><li>http://stneasy.cas.org/easy5/index.html </li></ul>
  7. 7. Scifinder Scholar <ul><li>An electronic version of Chemical Abstracts covering 1907 to the present </li></ul><ul><li>It is now searchable on the web </li></ul><ul><li>Users must set up an account with their NJIT e-mail </li></ul><ul><li>Only 2 simultaneous users allowed </li></ul><ul><ul><li>1 for web based version ( must setup an account) </li></ul></ul><ul><ul><li>1 for client based version (need to download software) </li></ul></ul><ul><li>Instructions at http://www.library.njit.edu.libdb.njit.edu:8888/njit-only/scifinder.php </li></ul>

  9. 9. Searching Capabilities <ul><li>ResearchTopic </li></ul><ul><li>Substance </li></ul><ul><ul><li>CAS Reg No. </li></ul></ul><ul><ul><li>Name </li></ul></ul><ul><ul><li>Molecular Formula </li></ul></ul><ul><li>Author Name </li></ul><ul><li>Author Affiliation </li></ul><ul><li>Chemical Structure </li></ul><ul><li>Reaction </li></ul>
