This is the sefer for those who are contemplating building an eruv, actually building an eruv,
checking an eruv, maintaining an eruv, and those who want to know how all of this is done.
Dr. Miller published the first edition of his Eruv Manual in 1982. He revised It in 2011 and
presents and explains the decisions Rabbi Moshe Heinemann made during the course of the
5.5-year struggle to build the Baltimore Eruv, 1975-1981. It carries the haskamos of Rabbi
Heinemann, Rabbi Chaim Jachter, author of the RCA’s Guidelines for Creating and Maintaining
a Kosher Eruv, and the series, Gray Matter, and Rabbi Yosef Gavriel Bechhofer, author of The
Contemporary Eruv: Eruvin in Modern Metropolitan Areas. Over 150 communities across North
America have consulted and relied upon this sefer for the planning, construction and
maintenance of their eruvin since 1982.
The sections of this sefer are entitled Relevant Halachos; Materials, Sources, Specifications,
and Costs, Eruv Administration, Construction Suggestions and Procedures, Effective Solutions
to Common Eruv Problems, Relevant Documents, and (130+) Stories from Baltimore’s Eruv
Dr. Miller speaks on eruvin to yeshivos, kollelim, and shuls. Eruv Manual may be purchased
