This collection of articles is the fruit of over sixty years of teaching and research by Professor Avraham Goldberg, one of the most prominent Talmud scholars of our generation. Professor Goldberg taught for decades in the Talmud department at the HebrewUniversity and was awarded the Israel Prize in Talmudic studies in 2000. In earlier years he was a student of Professors Louis Ginzburg and Saul Lieberman during his studies in New York, and later a student of Professors Y. N. Epstein and Hanoch Albeck in Israel.
