 The role of the members was to identify and collect documents, to prepare associated bibliographic and subject descriptions, to provide information services and products to users, and to archive and deliver copies of the grey literature documents.From 1980 to 1985, SIGLE was funded by the Commission of the European Communities (CEC).When CEC financial support ended in 1985, the national centres formed a network for the acquisition, identification and dissemination of grey literature called EAGLE, who became the producer of the SIGLE database.
