Responsa of Rabbenu Tam

This book contains one hundred and ninety-two written and oral responses by Rabbi Yaakov ben Meir, better known as "Rabbenu Tam," which were not included in the responses section of Sefer Ha-Yashar, compiled by his students. The first introductory chapters will be devoted to a concise presentation of his character, family, the stages of his life, and his teachers, while the other chapters will discuss his responses, their recipients, the sources in which the responses were found, the edition, and its contribution.

At the top of each reply is a short introduction that discusses the main contents of the reply and points out historical and other aspects that arise from it.
