Located primarily in shopping malls, B. Dalton competed primarily with Waldenbooks. Barnes & Noble acquired the chain from Dayton's in 1987 and continued to operate it until a late 2009 announcement that the last 50 stores would be liquidated by January 2010.
Bruce Dayton, a member of the family that operated Dayton's, a department store chain based in Minneapolis, Minnesota, founded the B. Dalton chain in 1966. He named the bookstore chain after himself, but substituted an L for the Y in his surname. The name B. Dalton was also chosen because it "connoted quality, dependability and authority."
B. Dalton expanded throughout the 1960s and 1970s, going from twelve stores in 1968 to 125 five years later, peaking at 798 locations in 1986. In 1968, the chain acquired Pickwick Books of California; they merged in 1979. B. Dalton had stores in 43 of 50 states in 1978, and was second to Waldenbooks (then the U.S.'s largest bookstore) in store numbers, but posted higher profits than its rival. A flagship store opened in Manhattan in December 1978, and between 1983 and 1986, the chain revived the Pickwick name as a discount bookstore.
