Toledot Yeshu ("The Life Story of Jesus") is a satirical counter-history presenting a "biography" of Jesus from a negative and anti-Christian perspective. It ascribes to Jesus an illegitimate birth, a theft of the Ineffable Name, heretical activities, and finally a disgraceful death. The narrative is transmitted in ca. 150 extant manuscripts, mostly in Hebrew but also in Aramaic, Judeo-Arabic, Yiddish, Ladino, and Judeo-Persian. All Hebrew and Aramaic manuscripts are edited in the present book and database: an unusual combination of a traditional critical edition with an electronic research tool. The book also includes a translation of selected manuscripts of all major recensions and an analytic introduction discussing the origins and evolution of the narrative's microforms. The database features a full-text search of all manuscripts as well as printing and downloading capabilities. The price includes access to the database (for one simultaneous user). Access for institution s is provided through the IP address, for private individuals through username and password. An activation code is enclosed in the book.
