Masekhet Soferim (Hebrew: מסכת סופרים), the "Tractate of the Scribes", is a non-canonical Talmudic tractate dealing especially with the rules relating to the preparation of holy books, as well as with the laws of Torah reading. One of the minor tractates, it is generally thought to have originated in eighth-century Land of Israel.[1] Being of late and uncertain date, it is now generally printed as Talmudic addenda.[2]
