One of the most venerable of Jewish book practices—Talmud study— has engendered a remarkable series of innovations by dint of the cascade of new media of the past century. These recent developments rest on a much longer history of practices centered on this core text of rabbinic Judaism. As scholars of the early modern period have noted, printed folios of the Talmud, first published in the late fifteenth century, expanded the engagement in rabbinic text study among jewish boys and men throughout the diaspora. beginning at the turn of the twentieth century, photo-offset reproductions of the 1880–1886 “Vilna Romm Shas” not only canonized this edition as definitive but also presented scholars with a daf of unprecedented standardization in both content and form. (The value invested in fixing the format of the daf is implicit in the “pin test,” in which yeshiva students are challenged to identify the words through which a pin, stuck into a page of the Talmud at random, passes on subsequent pages, a skill that relies on memorization of the text as well as knowing its placement on the page.) The standardized daf also facilitated the institution of Daf Yomi—inaugurated by Rabbi Meir Shapiro at the First World Congress of the World Agudath Israel, held in Vienna in 1923—as an international practice that both promotes and regulates Talmud study within a modular rubric.
