Jack Olsen was an American author and journalist who wrote thirty-one books and is said to have set the standard for the crime writing genre. The collection consists of correspondence, manuscripts, manuscript drafts and notes, source materials, reviews, and audiotapes from the early 1950s through the 1960s. The monograph series contains manuscript drafts and completed manuscripts for three of Jack Olsen's books: Black is Best, The Climb Up to Hell, and I'll Take Baseball. It also includes materials related to Over the Fence Is Out, a humorous book about his childhood that he published under the pseudonym Jonathan Rhoades, and works related to two unpublished novels. Most of the articles were written while Olsen was a staff member of Sports Illustrated.
