Jack London, the adventurer who wrote 19 novels, also was a prolific correspondent whose soon-to-be-published letters fill three thick volumes. In the more than 1,500 letters, to be published in October by the Stanford University Press, London covered topics ranging from socialism, which he championed ardently, to sailing and the Stanford-Cal football rivalry. He also reveals strong racist and sexist attitudes. Many of the letters were sentimental mash notes to his second wife, Charmaine Kitterdge London, and fatherly advice for his daughter Joan. In addition, he corresponded with many of his well-known contemporaries, including Joseph Conrad, Upton Sinclair and H.G. Wells. And like many other writers, London wrote notes to slow-paying publishers, to other writers comparing fees, and to friends and colleagues complaining of the high price of housing. Specifically, London was upset over the expenses he incurred building his ketch, the Snark, which he sailed to the South Pacific, and of maintaining his ranch in Glen Ellen, Calif. "The Letters of Jack London" is 1,800 pages long. Volume 1 covers the years 1896-1905; Volume 2 1906-1912 and Volume 3 1913-1916. The set contains 1,557 annotated letters and 112 photographs, many of them from the London family albums.
