Semak

Sefer Mitzvot Katan, so-called due to its being briefer than Rav Moshe of Coucy's Sefer Mitzvot Gadol, lists the commandments applicable in the post-Temple era, analyzing them and sometimes offering halachic rulings concerning them. It is divided into seven sections corresponding to the seven days of the week, so as to encourage the weekly review of the book. He was the son-in-law and student of Rav Yechiel of Paris and of Shmuel and Moshe of Evreux, and was the teacher of Rabbeinu Peretz.
