As the six founding partners of 17-year-old River Lights Bookstore in Dubuque, Iowa, prepare to close the store and dissolve their partnership on May 31, one of those partners, Sue Davis, is preparing to open River Lights, 2nd Edition on June 1. The 2nd Edition will open in a new location, with new fixtures, inventory, POS system, and sidelines. What will remain the same, said Davis, is the same great staff, the phone number, and the square footage -- 2,000 square feet. One of her former partners will continue to work at the store as a part-time employee.
