About STW Thesaurus

Purpose and Subject Coverage

  • STW Thesaurus for Economics is a controlled, structured vocabulary for subject indexing and retrieval of economics literature.
  • The vocabulary covers all economics-related subject areas and, on a broader level, the most important related subjects (e.g. social sciences).
  • In total, STW contains about 6,000 descriptors (key words) and about 20,000 non-descriptors (search terms).
  • All descriptors are bi-lingual, German and English.

  • STW helps users to search the ZBW catalogue ECONIS with the most suitable terms, because the holdings are indexed with its descriptors.
  • Having been developed as a general indexing and retrieval tool for economics publications, STW can be used by other organisations for indexing their own materials. Details for use are given on the STW online homepage.

History

  • STW has been developed thanks to a project that was funded by the Bundesministerium für Wirtschaft in the Nineties of last century.
  • Participating information providers were:
    • Deutsche Zentralbibliothek für Wirtschaftswissenschaften
    • GBI Gesellschaft für Betriebswirtschaftliche Information (now: GBI-GENIOS)
    • HWWA-Institut für Wirtschaftsforschung, Bibliothek (now: ZBW Hamburg)
    • ifo Institut für Wirtschaftsforschung, Bibliothek
  • These institutions still use the thesaurus for subject indexing.

Thesaurus Maintenance

  • Exclusive responsibility for the continuous maintenance of the STW lies with ZBW.
  • A regular editorial team verifies and decides on changes and updates concerning vocabulary and thesaurus structure.
  • Proposals by indexers and the current professional discussion are taken as sources for changes to be made.
  • The STW master file has been implemented into a thesaurus maintenance tool based on an inhouse development.
  • The consistent maintenance and revision is assured by carrying out plausibility checks and removing duplicate terms.
  • Each descriptor is given an ID-number which serves as a unique and inalterable key

  • The thesaurus team very much appreciates any proposal to improve vocabulary or thesaurus structure mailto:thes-team@zbw.eu.
