John Keel spent a large part of the ’50s writing for men’s adventure magazines, and then reworking the material into his first book, Jadoo. He summed up his experiences in an article for the April 1958 issue of Writer’s Digest: a fascinating look at the young writer, figuring out how to sell his stuff. He’s not writing here for the general public, but for fellow writers; and discusses the different types of adventure stories, and the tricky issue of blending fact and fiction to make a sale. He also gives the background for several of his published stories. The article ends with a list of men’s magazines, and their rates.
