Laws of kosher and related topics attributed to the school of Rashi. The "the school of Rashi" is material assembled shortly after Rashi's passing - responsa, teachings, communications, and practices in different collections. This literature, the greater part of which has survived, both published and in manuscript, is very ramified, and has acquired the general title of "the school of Rashi." The published collections are: Sefer ha-Pardes (Constantinople, 1807, ed, by H. L. Ehrenreich, 1924), Sefer ha-Orah (ed. by S. Buber, 1905), Siddur Rashi (ed. by S. Buber, 1911), Mahzor Vitry (ed. by S. Hurwitz, 19232), Likkutei ha-Pardes (Venice, 1519), Sefer Issur ve-Hetter (printed in part c. 1925), and the one published by Urbach (see bibl.). The connection of the Sefer ha-Sedarim (ed. by S. Elfenbein, in: Horeb, 11 (1951), 123–56) with Rashi is very much closer. Apart from all these there are extant about 350 of Rashi's responsa, collected from various sources by S. Elfenbein (1943). On the other hand, the works of "the school of Rashi" include additions of a very varied and diversified nature, from the teaching of the geonim, from the great Spanish scholars (chiefly in accordance with the Sefer ha-Ittim of Judah b. Barzillai al-Bargeloni), as well as from the early teaching of Erez Israel. It is still somewhat of a riddle how the teaching of Erez Israel was preserved and in what manner it found its way into various works of "the school of Rashi."

The special character of the books of "the school of Rashi" as halakhic collections caused them to pass through many hands, involving additions and omissions, so that the traditions and the practices have become confused. The many parallels existing among these books themselves show considerable differences. Rashi's influence as a ruling authority is also discernible upon the Italian authorities, both among the pupils of Isaiah di Trani I and also upon Zedekiah Anav, whose Shibbolei ha-Leket depends upon the work of Rashi and his school.
