These volumes contain most of Prof. Yaakov Zussman's essays. The essays include complex and extensive discussions in all areas of Talmudic literature from its beginnings to its scholars in recent centuries. Their collection in one book, accompanied by detailed indexes, presents to the reader the entirety of Prof. Zussman's research work, and at the same time makes it possible to locate and include discussions in distant places that were previously hidden from view.

The question of the manner in which the Tannaitic and Amoraic literature was passed on, orally or in writing, is of great importance in determining the basic cultural and historical facts in the world of the Sages, in understanding the development of the Oral Law and in the formation of its literature. In Jacob Sussman's revolutionary study, this complex subject was re-examined based on a thorough and profound study of various Talmudic sources, while comparing them with external, time-based evidence, published for the first time in Talmud Studies in 2004. It is published again in this book, along with detailed indices for source texts and various topics discussed therein.
