Live Lectures on the Laws of Shabbat
39 categories of work are restricted on Shabbat per the Talmud. These categories are referred to as the Avot Melachot.
This series of live lectures cover these categories with practical examples and real-life applications.
Please note: There are known audio issues with some sections (especially the second video), so I apologize in advance.
Incidentally, all of these will be eventually re-recorded in the future. I hope these lectures, nevertheless, serve as a good starting point for the interested student.
