As previously noted at the Seforim blog, Eruv Online has an excellent series on the history of eruvin controversies. In his most recent offering, he has posted the fifth segment of “History of City Eruvin − The Eruv in St. Louis.” For earlier posts, see 1,2,3,4.

On a related topic, see Rabbi Adam Mintz’s earlier post about “The Manhattan Eruv” at the Seforim blog.
