A groundbreaking new sefer! Years of research, hundreds of color, computer-generated 3D images, and a knack for accuracy and clarity have resulted in this first-of-its-kind, authoritative, comprehensive and practical guide which will be an invaluable resource in every beis medrash and every Jewish home. In-depth information for the Torah scholar includes: Hundreds of psakim never published before from gedolei haposkim in America and Eretz Yisrael; Contemporary halachic issues not discussed in other works; Extensive Hebrew footnotes citing all sources and teshuvos; Comprehensive biurim, providing advanced treatment of important topics. Q&A's for the interested reader include: "Can I carry on my front porch if there are steps leading to the street? Can I carry in my backyard on Shabbos? Can the bushes serve as a mechitzah? Why do some people use community-wide eruvin and others do not? I noticed that the string of the eruv in my bungalow got caught in a branch, is it still kosher? The Laws of an Eruv by Rabbis Shlomo Francis and Yonason Glenner contains a depth and breadth rarely found in an English language sefer, yet it is clear and comprehensible to every reader.
