There may be a lot of these short items this year, as Barnes & Noble adjusts their real estate portfolio — opening, but also closing, a number of stores. In Philadelphia, the chain will close their big two-story Walnut Street store in Rittenhouse on February 15 after more than 25 years there. They will move to a smaller location on Chestnut Street in the spring. Near Sacramento, CA, later this month they will close their store at The Promenade at Sacramento Gateway in Natomas.
