This book responds to a question that came to the author from Professor Maren Niehoff of the Hebrew University of Jerusalem: 'Have you written a simple introduction to your documentary theory and method, which can serve as a starting point for my students?' In this book are gathered eight of the more fundamental items of documentary theory and practice_three in theory, five in practice_for Professor Neihoff's students and anyone else who takes an interest in the formative history of Judaism. The documentary thesis of Rabbinic literature holds that the document_the Mishnah, Sifra, Lamentations, Rabbah, the Bavli, for example_forms the basic building block of the Rabbinic tradition. Excluded by that definition are sayings attributed to, and stories told about, named sages. These cannot serve in the reconstruction of the Rabbinic tradition, its literature, history, religion, and theology.
