Jules Verne
Jack London and Jules Verne
"We are surely not surprised to learn that Jules Verne gathered and systematically stored information in the fields of geography, natural science, and technology in his well organized collection of 20,000 cards and excerpts. However, it is somewhat unexpected to find, upon visiting the country house of Jack London in Glen Ellen near San Francisco, 188 card-index boxes alongside the writing desk of this writer who had an image of sailor, trapper, and adventurer."
