Rabbi Moshe Feinstein, the world renowned Talmudic and halachic authority, is best known as the premier halachic decisor of his time. To him, however, his major writings were these compendia of analysis and commentary on tractates of the Talmud. They display his encyclopedic grasp of Talmudic literature and his phenomenal and original powers. Rabbi Aharon Kotler said of Dibros Moshe, ""There is no significant concept or chiddush that cannot be found here."" Newly reprinted in a convenient 6""x9"" edition, each tractate complete in one volume.
