The Zamorano Eighty is a list of books intended to represent the most significant early volumes published on the history of California. It was compiled in 1945 by members of the Zamorano Club, a Los Angeles-based group of bibliophiles. Collecting first editions of every volume on the list has become the goal of a number of book collectors, though to date only four people have completed the task.
The Zamorano Club was founded in 1928 and named for Agustín Vicente Zamorano, the first printer in California. A series of committees of Club members, including former American Smelting and Refining Company executive Henry Raup Wagner and bibliographer Robert Cowan, assembled a list of a hundred books, eventually whittled down to eighty. During this process, Cowan died, and his Bibliography of the History of California and the Pacific West was added to the list as a tribute.
