Today, the STW is maintained by an editorial board situated at the German National Library of Economics (ZBW) and used by scientific institutions, by documentation centers for economics and business and by GBI-Genios, a provider of business information databases and one of the co-creators of the thesaurus. Its 5,800 descriptors in German and English are presented within a taxonomy of 500 classes to offer an easy navigation along the lines of categories widely accepted in the profession. 17,000 non-descriptors (mainly in German) direct users to the preferred terms. The concepts of the thesaurus are richly interconnected through 15,000 “broader/narrower” and 10,000 “related” links
