3. Contents of Lecture What are chemists looking for? Where to look? Chemical Names Web of Science SciFinder Scholar Other resources

4. Assignment Summary Web of Science SciFinder Scholar Factual source from class web page

5. Robert Tomaszewski, Georgia State University Libraries

6. Information Searches What you use depends on the type of information you need Factual information  Physical data, Spectra Research Literature  Synthetic pathways, function and structure, pharmacokinetics

7. Information Sources Factual information  Handbooks, encyclopedias Research Literature  Periodical indexes and databases Can be print or electronic Access method based on organization’s resources

8. Why not Google? Easy to use But what about the junk?  Google Scholar Google Scholar Hard to specify Try looking for a chemical compound

9. How do we identify a chemical? Brand name  Aero,Hicophor PR, Pluragard Trivial name  Melamine Structural name  1, 3, 5-Triazine-2, 4, 6-triamine  2, 4, 6-triamino-s-triazine

10. How do we identify a chemical? Formula – C 3 H 6 N 6 CAS RN – 108-78-1 Structural drawing

11. Research Literature Article Databases, Periodical Indexes, Index and Abstracting Services Web of Science SciFinder Scholar

12. Web of Science Multidisciplinary database indexing over 7000 journals Heavy emphasis on science Includes 800 chemistry journals Goes back to 1900

13. Web of Science Can search by author, keyword, or cited reference Very tricky to search by chemical name (no control of names) Formula searches are also very difficult

14. Using Web of Science

15. Chemical Abstracts (CA) Indexes 9,000 journals plus patents, theses, technical reports, conference papers, books International and multidisciplinary in coverage Can search by author, topic, chemical formula or name, structure Goes back to 1907 Part of an online system called “SciFinder Scholar”

16. SciFinder Scholar 6 inter-linked databases CAplus – Chemical Abstracts; includes some pre-1907 material Medline – references to the medical journal literature from 1950s to present

17. SciFinder Scholar CAS Registry – basic information on ~27 million compounds CASREACT – information on over 8 million single and multi-step reactions CHEMLIST – regulated chemicals CHEMCATS – catalog of commercially available compounds and their suppliers

18. SciFinder Scholar Requires additional software Can only be searched on campus Limit of two users

19. Using SciFinder Scholar
