In 1909 Louis Ginzberd published a series of books, which were destined to become classics of Jewish literature. Pulling from an enormous amount of sources: Midrash, Kabbalah, Talmud, Pseudopigrapha, Hasidism, etc. Louis Ginzberg assembled a phenomenal series that brings down Jewish philosophy and theology. The Alef Tav Torah Institute has recognized these works as invaluable for Jewish education and has re-released these works for the general audience of modern society and academia. We hope that the publishing of these works will bring great nachas to Rabbi Ginzberg z'l as his great endeavor to create such a work will continue on.
