"Adam Mintz's study on Eiruv in America provides a sweeping view of the history of this important aspect of Sabbath observance and a detailed study of early attempts to construct Eiruvin in North America. His work puts the resurgence of this aspect of the development of Orthodox life in the late 20th century into a completely new perspective. Mintz shows that study of the modern history of Jewish law can contribute greatly to understanding the development of orthodoxy in America."

- Lawrence H. Schiffman, Judge Abraham Lieberman Professor of Hebrew and Judaic Studies, New York University

"This book is rather accessible given the topic's dense legal history. ... Mintz does an excellent job of going through the history of eruvin, what concerns different communities had, and how those communities did or did not tackle those issues. ... The laws of eruv are too often relegated to Hebrew Halakhic texts, that Building Communities has merit in possessing even if it were not as accessible as it is."

- Andrew Lillien, AJL News & Reviews

"Adam Mintz's excellent work, Building Communities: A History of the Eruv in America, is a splendid example of how halakhic texts can be employed and interpreted to better inform us of widespread historical matters. ... While the author discusses the legal-halakhic issues that challenged rabbinic scholars in those cities, he deftly highlights the larger practical matters that shaped and often divided these communities. ... Adam Mintz has written a highly informative work that presents the reader with a wide range of halakhic sources and analysis, while offering insight into their historical significance. The work is a notable contribution to the history of halakha and the experience of Orthodox Jewish life in America."

"In this well-researched and erudite book, Adam Mintz, a distinguished pulpit rabbi and scholar, provides an invaluable survey and guide to the history of eruv establishment from the Mishna to the modern era...Mintz briefly discusses the dramatic expansion of community eruvim throughout the USA, as well as the bitter opposition these structures frequently provoked in communities with predominantly non-Jewish and non-Orthodox residents. This opposition has been described piecemeal in articles dealing with events in towns such as Palo Alto, California; Tenafly, New Jersey; and Westhampton, Long Island. Following on Mintz's excellent book, a subsequent more book length study of the further development of these communities is merited and would be of interest to readers of Contemporary Jewry."

-- Philip Fishman, Contemporary Jewry

"More than 200 American Jewish communities boast an eruv, permitting observant Jews to carry within its boundaries on the Sabbath. In this long-awaited volume, Adam Mintz explains the early history of the eruv in America, focusing on St. Louis, New York, and Toronto, including the fierce halachic disputes surrounding these projects and their relation to earlier eruv projects in Europe. Learned, readable and comprehensive, the book makes an important contribution to the history of American Orthodoxy and will be welcomed by all students of the eruv."
