ECLAS

European Commission Library Thesaurus

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.
