AGRICOLA publishes new thesaurus

AGRICOLA, the National Agriculture Library (NAL) catalog, has published a new thesaurus. Some students in my library instruction have used the NAL thesaurus to improve their search terminology. The thesaurus lists the controlled vocabulary for the online catalog. Using the controlled vocabulary can improve your searches. Changes to the NAL Thesaurus are as follows (from USDA National Agriculture Library http://agclass.nal.usda.gov/agt/dne/whatsnew.shtml):

Terminology associated with fuels, chocolate manufacture, bodies of water and the US National Forest System were expanded this edition. The taxonomic classification of viruses was enhanced by the addition of acronyms used by the International Committee on Taxonomy of Viruses (ICTV).

NAL provides a list of new terms as well as a list of replaced terms. For example, the term "Tetrapedia" has been replaced by "Tetrapedia (Algae)."
