Yalkut Yosef consists of some thirty volumes that summarize the halakhot that every Jew needs to know in order to observe the mitzvot properly. It covers the activities of a Jew on weekdays, on Shabbat and on Yom Tov, according to the halakhic rulings of Maran the Rishon Letziyon, Harav Ovadya Yosef, shalit”a. It is written in a clear, straightforward reader-friendly style and is useful for anyone with or without background in these subjects. Almost 100,000 copies of Yalkut Yosef have been sold to date, making it a veritable best-seller of Torah literature. It has already been translated into several languages.

HaKeter Institute employs a staff of experts to work on this project, which is much more than a quality translation. The Hebrew text of this new edition has been completely re-edited for clarity and preciseness, and all sources have been reviewed for accuracy. The English text includes footnotes summarizing the discussions of Maran the Rishon Letziyon that lead to his halakhic decisions and other related sources. Some footnotes discuss issues that were not covered by the Rishon Letziyon in any of the many sefarim he authored, and they cite other contemporary Poskim, such as Harav Shelomo Zalman Auerbach and Harav Ben Tziyon Abba Shaul, zikhronam livrakha. Each subject is prefaced with an explanation of the halakhic concepts presented therein, to enable the reader to fully appreciate the halakhot he will be studying.

The books have been prepared with a focus on our contemporary lifestyle and the halakhic problems it may pose. Many halakhot address circumstances such as hotel stays, businessmen away from home, financial investments, and air- or land-travel. When the correct ruling does not seem crystal-clear, we at HaKeter Institute have the unique privilege of being able to present our questions to Maran the Rishon Letziyon, who gives them careful consideration and renders his decision specifically for publication in this series of Yalkut Yosef.

HaKeter Institute has included some important added feature to each volume of Yalkut Yosef, such as Megillat Antiokhus in the volume presenting hilkhot Hanukka, Megillat Esther with the Keter Malkhut commentary in the volume presenting hilkhot Purim, and a guide to the kosher Pesah kitchen and its utensils in the volume presenting hilkhot Pesah.
