description: Dating from 1978 when catalogues of the Central Library of the Commission
  of the European Communities (now the European Union) were computerised, ECLAS is
  a thesaurus created by the Central Library of the Commission of the European Communities
  for indexing the publications and documents acquired by the Central Library of the
  Commission. ECLAS was based on the Macrothesaurus of OECD and complemented by the
  ILO thesaurus. After creation of EUROVOC in 1984, convergence started in order to
  bring ECLAS in line with EUROVOC, but it was never complete. ECLAS contains nineteen
  areas of interest in a hierarchical tree structure consisting of four levels. ECLAS
  is fully available in English and in French. The OP COMM ECLAS is maintained by
  the Publications Office of the European Union on the EU Vocabularies website.
