"The Ligue des Bibliothèques Européennes de Recherche (LIBER) is the principal association of the major research libraries of Europe. It was founded in 1971 under the auspices of the Council of Europe. Its current membership includes research libraries of more than forty countries. LIBER membership is not restricted to the area of the European Union, and membership of research libraries outside the European Union is encouraged.
LIBER actively promotes co-operation with all library-related organizations. It has strong links with the Council of Europe, the Commission of the European Communities (CEC), and the International Federation of Library Associations and Institutions (IFLA), as well as with national library associations."
