You must turn in your answer sheet no later than 12:00 noon on Tuesday, November 11, 1997. No exceptions.

1. It is impossible to do a citation search in Science Citation Index for an article published prior to 1988.

False. You can do a citation search on any article (or any primary document, for that matter) regardless of when it was published.

2. In order to do a citation search in all available database versions of Science Citation Index, it is necessary to know the name of the author who is listed first on the article that is used as a search key. That is why it is impossible to find out who has cited all of a given author's publications when that author may not be listed as the first author on some of the publications.

False. With STN and the new Web of Science versions of Science Citation Index, you can do such a search relatively easily.

3. Using keywords to perform subject searches results in much more precise references being retrieved in a database search than does using the controlled vocabulary that indexes items in the database.

False. Just the opposite. The reason for using a controlled-vocabulary approach (such as you do when you use the Index Guide to CA, for example) is to find the exact words that have been used by the indexers to provide the best access to the material.

4. Under no circumstances does the American Chemical Society allow the full form of an author's given names (first and/or middle names) to be used for a reference in the bibliography of an article submitted for publication in an ACS journal.

False. The new second edition of The ACS Style Guide does permit this.

5. It is ok to search the term "Gypsy Moth" directly in the most recent five-year collective General Subject Index to Chemical Abstracts.

False. Better go to the Index Guide first, where you will be directed to the genus/species name Porthetria dispar, the phrase to be searched in the General Subject Index.

6. It is ok to search the chemical name "disparlure" directly in the most recent five-year collective Chemical Substance Index to Chemical Abstracts.

False. Disparlure in the Index Guide leads to Oxirane, 2-decyl-3-(5methylhexyl)-, cis [29804-22-6], the proper term to search in the Chemical Substance Index.

7. The correct Hill Formula order of the molecular formula for sulfuric acid when searching the Chemical Abstracts Formula Index is: H2SO4.

False. It looks good to a chemist, but the proper Hill Formula order is: H2O4S. (The H comes first just because it is the earliest in the alphabetical sequence.)

8. The correct Hill Formula order of the molecular formula for bromobenzene when searching the Chemical Abstracts Formula Index is: C6H5Br.

True. If Carbon is present, it comes first, followed by H if it is also present. If carbon is not present, arrange the elements in alphabetical order.

9. STN Express permits structures drawn offline to be uploaded for searching in the Chemical Abstracts Registry File and other structure-searchable files on STN.

True.

10. Only two-dimensional structure searches can be performed on the Beilstein CrossFire system, whereas the STN version of Beilstein allows the stereochemistry to be searched.

False. You can search the stereochemistry on both systems.
