Squirrel Hill bibliophiles can finally ease their phantom limb symptoms, no longer reflexively turning their steps toward the long-shuttered Barnes and Noble. With the opening of Classic Lines, located at 5825 Forbes Avenue in the previous home of Capriccio Boutique, the neighborhood now boasts two independent booksellers. Classic Lines is a general interest bookstore with volumes in all subject categories. The store’s more than 5,000 books are roughly 80 percent used and 20 percent new; Iddings intends to shift the ratio to be about 60 to 40 percent. When asked about Amazing Books, another independent bookstore that opened on Murray Avenue a few months ago, Iddings’ response smacks more of camaraderie than competition.
