New York’s Coliseum Books wasn’t pretty or comfortable. But it was a great place to find books (and isn’t that sometimes the point?). So Coliseum was lamented when it lost its lease last year and went out of business. Now it’s reopening on 42nd Street, across from the public library. How to compete with the Barnes & Noble stores on every street corner? Well, there’ll be books you probably won’t find at B&N. And a coffee shop (the investors insisted).
