BIOSIS, file segment of TOXCENTER reloaded and enhanced

The BIOSIS file segment in TOXCENTER has been reloaded. A number of enhancements have been implemented that make the content of the BIOSIS file segment in TOXCENTER more complete and easier to search. The enhancements made as a result of the reload include:

1. The Biosystematic Codes (BC) used for organism searching have been restructured and applied consistently across the entire database from 1969 to the present. As a result, over 240 Biosystematic Codes were changed.
   
   For additional information about the Biosystematic Code conversion, as well as a list of all old Biosystematic Codes, all changed Biosystematic Codes, and all changed Organism Classifier Terms, visit: http://biosis.org/productupdates/index.html.
2. Concept Codes (CC) and additional context-sensitive indexing for the Organism (/ORGN) and Index Term (/IT) fields have been extended to the entire database from 1969 to the present. The /ORGN field now includes Organism Super Taxa terms and Taxa Notes Superterms for appropriate records and the /IT field now includes Major Concepts and other types of indexing terms.
3. New terminology and relationships are reflected in the thesauri for four fields: Biosystematic Codes (/BC), Controlled Term (/CT), Geographic Term (/GT), and Organism (/ORGN).
4. The search and display of the Organism (/ORGN) field has been improved, and the data for each group of organisms is located together. Biosystematic Codes (BC) and text terms are searchable using either the /ORGN or /BC field code. Using either ORGN or BC displays the ORGN field.
5. The Diseases subfield in the Index Term (/IT) field includes both the BIOSIS indexing terms and the corresponding MeSH terms for specific diseases, if available. Also, for many of the MeSH terms, MeSH Tree Numbers have been identified and are searchable in the Controlled Term (/CT) field.
6. The E-mail Address (/EML) field now contains information for records from the BIOSIS file segment.
7. The Other Source (/OS) field now contains GenBank@ and other sequence database numbers for records from the BIOSIS file segment.
8. One search and display field, Corporate Name (/CO), is no longer available. Information previously found in the Corporate Name field is now available in the Index Term (/IT) field with other miscellaneous descriptors.
9. Information for records from the BIOSIS file segment is no longer available in the Summary Language (/SL) field.

Because of the changes to the Biosystematic Codes and the search field changes, you should review your search strategies and make the appropriate changes if you currently have an automatic current-awareness alert (SDI) set up or any saved queries in TOXCENTER.
