The Tosafot quote principally Rashi (very often under the designation "ḳonṭres" [= "pamphlet", Rashi initially published his commentary in pamphlets]), many of the ancient authorities (as Kalonymus of Lucca, Nathan b. Jehiel, and R. Hananeel), some contemporary scholars (as Abraham b. David of Posquières, Maimonides, Abraham ibn Ezra, and others), and about 130 German and French Talmudists of the twelfth and thirteenth centuries.
