What's New in 2017 Edition
 
The 2017 edition is the sixteenth edition of the National Agricultural Library Thesaurus; first edition was released by the National Agricultural Library in 2002. Terminology is available in both English and Spanish versions. Taxonomic terms from every biological kingdom were expanded in this edition, along with common names of species. Major updates are done in the classification for organisms, resulting in an 8 Kingdom structure (Animalia, Archaea, Chromista, Protozoa, Eubacteria, Plantae, Fungi, and Viruses & Viroids) in alignment with Ruggiero et. al. (2015) “A Higher Level Classification of All Living Organisms” and other authoritative resources. Plant species were added following taxonomic verification by the Germplasm Resources Information Network (GRIN). Plant taxonomy was updated by consulting Angiosperm Phylogeny Group IV (2016). The Report of the International Committee on Taxonomy of Viruses (2015 release) was the authoritative reference for new viruses included in this edition. Algae taxonomy was expanded following taxonomic verification from Algaebasee. Bacterial taxonomy was updated and expanded by consulting Bergey's Manual of Systematics of Archaea and Bacteria, bacterio.net and other authoritative resources. Please visit our bibliography page for reference works, databases, thesauri and internet sites that were used in the preparation of the thesaurus and glossary.Other subject areas expanded include terms in forestry, agricultural technology, fisheries, cell biology, food sciences, genetics, plant diseases, enzymes, chemicals, health and pathology. The 2017 edition contains 277 new definitions, which appear in the thesaurus and separate glossary.

Please consult the list of new terms for this edition.

Thanks are extended to AgNIC members, IICA partners, Dr. John Wiersema at GRIN, entomologist Gary Miller and his team at ARS, and to all those who proposed suggestions for changes to this edition. Users are encouraged to send us comments so that we may continue to improve this resource.
