The National Authorities of the Czech Republic Portal concentrates information on creating and using national authority files of all types in one place.                

The National Authorities of the Czech Republic (NA CR) Portal, a project of the National Library of the Czech Republic, concentrates in one place often fragmented information on the issue (in the broadest sense of the word) of the creation and use of national authority files of all types.

  • Name authorities include a set of personal and corporate authorities (names of institutions and events), family authorities, and author/name authorities for use in name and subject processing of documents.
  • Subject authorities include sets of thematic, geographical and formal authorities; access to a set of chronological authority terms is under development. Within this database, a set of Conspectus groups (both Czech and English versions) and a set of authorities for places of publication of old prints are also published.
  • Title authorities for Czech book production and musical works (music and sound recordings) include authorities for unified titles and, by methodology, author/title authorities. Title authorities are used in both name and subject processing.
