This first of the ultimately three-volume Who’s Who in Islamic Studies presents the scholarly world at long last with its own biographical encyclopaedia. Taking as a starting point the inventory of authors from the renowned Index Islamicus, the author, Wolfgang Behn (Berlin), has systematically collected numerous data on the lives and works of the tens of thousands of authors listed in the Index Islamicus from 1665 to 1980. This Biographical Companion will be an indispensable reference tool for the serious student and scholar of Islamic Studies. It enables the user to quickly gain knowledge on the life, work, and professional background of almost every major and minor author, and thus to place each author in his/her proper perspective. A tremendous achievement and a true must for every library.
