Why should you use CAB Thesaurus?
Build complex searches in the new, improved CAB Thesaurus – the authoritative list of CABI’s indexing terms. This tool can help you identify search terms and enable you to build a search profile using narrower terms. The search query can then be sent directly to CAB Direct, at the click of a button.
The CAB Thesaurus can be used to index digital or physical text, objects and collections. In an electronic environment, this means that different types of content within a subject area can be efficiently retrieved using a simple search strategy. Indexing with the CAB Thesaurus can enable highly effective searching and retrieval of your information.

What's new in the 2018 edition of CAB Thesaurus?
The updated version, with 2,775,794 terms, includes 172,972 distinct concepts (preferred terms) and 136,827 synonyms, as well as translations of these from English into ten European languages. These improvements make CAB Thesaurus the largest of its type in existence with at least twice the content of similar resources.
A number of important additions and revisions ensure the search tool remains relevant for various research applications. 5201 translations added of non-taxonomic terms from English, particularly into German (2805), French (1063), Spanish (567), Portuguese (447) and Dutch (304), focussing on products and commodities, chemicals, and diseases terminology to ensure the hierarchies linked up well. In total, over 11,518 new terms were added.
The revision of dicot plants continues, using the current APG IV system for classification, with revisions of 52 families down to species level.
A new category code for natural processes has been added with 923 terms now classified under this category.
CAB Thesaurus and open data
In September 2016 at the GODAN Summit in New York, CABI CEO, Dr Trevor Nicholls detailed how CABI will collaborate with organizations like the USDA to create a Global Agricultural Concept Scheme, linking agricultural descriptive frameworks to build an open data resource, based on CAB Thesaurus.
