List of Replaced Descriptors

The annual updating of the thesaurus with a new edition enables:

  1. Replacement of terms with more up-to-date terminology
  2. Replacement of ambiguous terms
  3. Correction of errors

However, these changes may impact the ability to search previously indexed database records for those who use the thesaurus as a controlled vocabulary. The Thesaurus Staff makes all effort to replace deleted or modified preferred terms with a cross-reference to the new preferred term. There are 210 replaced preferred terms between the 2019 and 2020 editions.
