In 1963, the European Community established an extended network for the dissemination of information to the public. The European Documentation Centres are part of this network, situated in the member states of the EU, as well as in other parts of the world, in order to promote the official publications of the EU. Today there are 544 Documentation Centres all over the world, of which 324 are to be found in member states. There are nine Documentation Centres in Greece, operating mainly in cities hosting universities.
