Ovid Technologies, Inc.2006 AGRICOLA (agra) Reload News |
AGRICOLA has been reloaded. The Reload includes a new thesaurus, the National Agricultural Library Agricultural Thesaurus. The data has been expanded to include records from 1970 forward, and there are now six segments rather than two. The Category Codes have been updated, and improvements have been made for better data display, diacritic display, improved metadata and linking, removal of duplicate records, and display of IP data not serials data.
In addition, the Classification Codes tool has been updated. To access the Classification Codes tool, you now just need to select the tool and click the Perform Search button. A full list will display.
Finally, Ovid has made the following changes to the database:
