History - Documentation of Changes

A thesaurus is by its very nature in need of constant further development, i.e. it is permanently work in progress.

The Thesaurus Editorial Team discusses adaptations to new developments in the field of bioethics, to new concepts, questions and new terminology. All changes relevant to indexing or search routines are comprehensively documented in a History file accompanying each new Thesaurus edition. The History includes information on new, rephrased and deleted descriptors. Entries for rephrased descriptors also show the former formulation and the period during which it was used as descriptor.
