Peri Megadim.

Super-commentary to the Shulchan Aruch-Orach Chaim, here in two parts: Mishbetzoth Zahav on the Taz [Turei Zahav] and Eshel Abraham on the Magen Abraham. The author was universally acclaimed as the preeminent Halachic decisor of his generation and this work is published in all standard editions of the Shulchan Aruch. Although published in two parts, the pagination is consecutive. This first edition contains approbations and an introduction thanking his wife by name (Toiba) subsequently lacking in later editions.
