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.
- 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.
- 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:email@example.com.
