It's tough to choose a chain over a mom-and-pop store, but for selection of children's books, Barnes & Noble is tops. Any book the store doesn't have on its shelf, it can get pretty darn quickly. They've got all the classic stories and even the latest favorites. When asked about a copy of a certain popular children's book series, one independent bookstore operator said it could be several weeks or longer before any arrived. Barnes & Noble had several copies in stock, and its kids corner seemed to have as many titles as the specialty stores do.
