The Torah library is a colossal collection comprising hundreds of thousands of titles. Among them are books that had an incredible influence—some of them once absolute classics—but are unfortunately rarely read today. In honor of Shavuot, the festival of the Giving of the Torah, we present a list of 10 fundamental Torah books that deserve a return to the spotlight.
1. Maimonides’ Introduction to His Mishnah Commentary
The Torah is divided into the Written Law and the Oral Law. But what exactly is the Oral Law? How did it come to be, and what does it include? When and how do disagreements arise in Torah law? The answers to these foundational questions can be found in Maimonides’ Introduction to his Commentary on the Mishnah, originally written in Judeo-Arabic and first translated into Hebrew by medieval scholar Rabbi Yehuda al-Charizi. An introduction might not sound like essential reading, but don’t be fooled: this one remains the basis of our understanding of the Oral Law to this day.

2. Letter of Rav Sherira Gaon
In the late 10th century, the Jewish community of Kairouan, Tunisia, wrote to Rav Sherira Gaon of Babylonia with a bold request: a complete history of the Mishnah, the Talmud, and all the major Torah leaders up until that point. Rav Sherira rose to the challenge, and in a detailed letter written in Aramaic, he traced the transmission of Torah across the previous thousand years. Many scholars of the Geonic era are known to us only from this letter.

3. Sefer Mitzvot Gadol (“Great Book of Commandments”)
In the 13th century, French Talmudist Rabbi Moshe of Coucy authored Sefer Mitzvot Gadol (also known by the acronym “Semag”)—a two-part work cataloging all the positive and negative commandments and their laws. A landmark in its time, it served as the principal halachic code for Ashkenazi Jewry for three centuries, until Rabbi Yosef Caro authored the Code of Jewish Law. The Semag was so popular that it was one of the first Jewish texts ever to be printed, in Rome in 1473–1475.
4. Kav Hayashar (“Honest Measurement”)
Kav Hayashar is a classical ethical work by Rabbi Tzvi Hirsh Kaidanover, first printed in 1705 and reprinted many times since. The book won widespread popularity thanks to its clear, accessible language, its practical guidance, and the many meaningful stories woven throughout. It was studied by both Ashkenazi and Sephardic Jews, as evidenced by the fact that it was translated into both Yiddish and Ladino.
The first word of the title—Kav (קב)—has the numeric value of 102, corresponding to the number of chapters in the book.

5. Menorat Hama’or (“Menorah of Light”)
Another classical ethical work, predating Kav Hayashar by some 300 years, is Menorat Hama’or, written by the Spanish scholar Rabbi Yitzchak Abohab. The book gathers the wealth of moral and inspirational material found scattered throughout the Talmud and Midrash—which, as the author notes in his introduction, is too often overlooked—and organizes it into seven broad topics, corresponding to the seven branches of the menorah: thought, speech, deed, Torah, repentance, peace, and humility. The work became immensely popular, printed numerous times and translated into Yiddish, Ladino, and German.
6. Tashbetz Katan
In 1286, the great sage Rabbi Meir of Rothenburg was arrested and held for ransom. During the seven years of his imprisonment until his death, he was frequently visited by his student Rabbi Shimshon, who carefully recorded his teacher’s conduct and compiled his observations into a slim work called Tashbetz. Due to its brevity and practicality, the book became a shortened Code of Jewish Law of sorts. For centuries, it was a staple in every German Jewish home, sitting alongside the prayer book and the Chumash (the Five Books of Moses).
“Tashbetz” is an acronym for “Talmid (student) Shimshon ben (son of) Tzadok.” “Katan” (small) was added later, to differentiate it from a longer work of the same name authored by Rabbi Shimon ben Tzemach.

7. Mavo L’Talmud (“Introduction to the Talmud”)
If you want to understand a book, you first need to know its rules and become familiar with its language. This is especially true of the Talmud, whose dense, cryptic style can be daunting even to experienced students. To help learners navigate this seminal work, Rabbi Shmuel Hanagid—an Egyptian 13th-century scholar1—wrote a short treatise known as “Mavo L'Talmud.” Many similar guides have been written since, but his was among the first, teaching the ropes of the Talmud to thousands of students.

8. Sefer Habrit (“Book of the Covenant”)
In the 18th century, the winds of modernity swept through Europe, bringing with them new technologies, scientific discoveries, and a flood of secular books—most of which were laced with ideas at odds with Torah values. Observant Jews who wanted to engage with this new world of knowledge had few good options. That’s why, when Rabbi Pinchas Eliyahu Horowitz published Sefer Habrit in 1797, it became an instant sensation. Drawing on some 150 books of general science while grounding everything in traditional Jewish perspectives, it offered readers a Torah-true gateway to the wider world of knowledge—and remained the only such work for nearly two centuries.
Like Menorat Hama’or and Kav Hayashar, this book was translated into both Yiddish and Ladino to make it accessible to both Ashkenazi and Sephardic Jews.
9. Sefer Ha’ikrim (“Book of Principles”)
Written by 15th-century Spanish scholar Rabbi Yosef Albo, Sefer Ha’ikrim is one of the most influential works of Jewish philosophy ever written. While Maimonides famously enumerated 13 principles of Jewish faith, Rabbi Albo takes a different approach, distilling them into 3 core ideas upon which all of Judaism rests: the existence of G‑d, the Divine origin of the Torah, and Divine reward and punishment. First published in 1485, this classic has been reprinted many times and translated into multiple languages, including Latin, German, and English.

10. Chovot Halevavot (“Duties of the Heart”)
While the Torah library is rich with volumes of Jewish law, most of them cover the duties of the body’s external limbs—the actions we must or must not perform. What about the duties of the heart: to believe in G‑d, serve Him, trust Him, and love Him? Noticing that no such work had yet been written, 11th-century scholar Rabbi Bachya ibn Pekuda set out to fill that gap with Chovot Halevavot. Originally written in Judeo-Arabic, the book has remained a classic ever since, and many great Jewish leaders studied it and urged their followers to do the same.
In recent years, one section in particular has taken on a life of its own: Shaar Habitachon (“The Portal of Reliance on G‑d”), which has become a bestseller and is available today in numerous translations and editions.
