Mishneh Halachos

Mishneh Halachos is an 18-volume set of responsa (Hebrew: שאלות ותשובות), which was authored by the Rabbi Menashe Klein, Rabbi of Ungvar.

These responsa span over a course of about 50 years. Mishne Halachos covers every aspect of the Torah. In the early 1960s, he published a book entitled Mitzvos Hamelech (Hebrew: מצות המלך), a sefer designated to learn each day, on the 613 Mitzvos. This program is called Mitzva Yomis.
