After a series of mergers and bankruptcies in the American bookstore industry since the 1990s, Barnes & Noble stands alone as the United States' largest national bookstore chain. Previously, Barnes and Noble operated the chain of small B. Dalton Booksellers stores in malls until they announced the liquidation of the chain. The company is known for large retail outlets, many of which contain a café serving Starbucks coffee and other consumables. Most stores sell books, magazines, newspapers, DVDs, graphic novels, gifts, games, toys, music, and Nook e‑readers and tablets.
