The Institute of Advanced Legal Studies was founded in 1947, although the idea for a national law library and centre for research was conceived over 50 year before this. Since its foundation, the IALS has developed a library of international standing and has been able to foster and promote legal research not only in Britain but around the world. It performs a unique role in the United Kingdon and the Commonwealth and an increasingly important one in Europe.;To commemorate the Institute's jubilee and the inaurgation of the Society for Advanced Legal Studies, the present Director has assembled a series of papers which not only trace the Institute's development into an institution for the advancement of legal research of world-class standing, but also illustrate the depth of support that it enjoys.
