L. Sprague de Camp - Fletcher Pratt - The ​Castle of Iron
The ​Harold Shea stories are parallel world tales in which universes where magic works coexist with our own, and in which those based on the mythologies, legends, and literary fantasies of our world and can be reached by aligning one's mind to them by a system of symbolic logic. In The Castle of Iron, the authors' protagonist Harold Shea visits two such worlds, first (briefly) that of Samuel Taylor Coleridge's poem Kubla Khan and second that of Ludovico Ariosto's epic, the Orlando Furioso.

L. Sprague de Camp - Fletcher Pratt - The ​Compleat Enchanter
The ​Mathematics of Magic was probably the greatest discovery of the ages - at least Professor Harold Shea thought so. With the proper equations, he could instantly transport himself back in time to all the wondrous lands of ancient legend. But slips in time were a hazard, and Shea's magic did not always work - at least, not quite as he expected... This omnibus volume of all of the Magical Misadventures of Harold Shea contains The Incomplete Enchanter, The Wall of Serpents and Castle of Iron
