But everything changes, and that will, too. Wisconsin-based Book World, which somehow managed to be the fourth-largest book chain in the U.S., will soon vacate storefronts across the Midwest. The company cited the loss of sales to online competitors. So small communities like Rice Lake, Sturgeon Bay, Shawano and 17 others in Wisconsin will lose one more thread of local fabric. A few may have a local bookstore tended by dedicated owners. Most will go without, and their communities will be the less for it. Hopefully a new model will emerge in these towns.
