Y. Rafael, ed., Sefer hamanhig, Jerusalem: Mosad Harav Kook, 1978, 2 vols.—This is a sumptuous, critical edition of the work by Abraham b. Nathan of Lunel, based on the Oxford manuscript, supplemented by a number of others. There is a learned introduction and notes and a full scientific apparatus. The author, as the editor demonstrates, was the first to record all the various local customs. Apart from its intrinsic importance and interest, the work is essential for an understanding of the whole question of the role of local custom in the development of the law. L.J.
