Other ABA
For seven years 1980 to 1986, there were two distinct sets of American Book Awards. The other is now officially one stage of the National Book Awards (NBA) history.
The National Book Foundation is responsible for the National Book Awards (U.S.) from 1989 and officially recognizes a continuous NBA history from 1949/1950. Part of that history is those so-called American Book Awards that formally replaced the National Book Awards after their 1979/1980 cycle, were revamped for 1984, and were renamed "National" in 1987.
The American Book Award is also unrelated to the American Booksellers Association (ABA), although that organization maintains a complete list of award winners that is readily available. Since the 1970s that trade group is also unrelated to the National Book Awards, which it established in 1936 and jointly re-established them as book industry awards in 1950.
