My first job was in a superb suburban library in the Midwest which was open from 9am-9pm (except on sundays which was noon-5pm).

However I now live in NYC, the city that never sleeps, and can’t believe that local libraries in Manhattan are generally open 10am-6pm making them hard for students to visit if they have extra-curricular activities and nearly impossible for anyone working to ever take advantage. The hours alone seem to indicate the libraries are mostly for the retired or unemployed.
