LIBER (Ligue des Bibliothèques Européennes de Recherche) is the main research libraries network in Europe.

Founded in 1971 as the Association of European Research Libraries, the 'Association' was dissolved at the Annual General Assembly in Toulouse, France, on Friday 3 July 2009, to make way for the 'Foundation' (Stichting LIBER), with its registered office in The Hague, The Netherlands.
