The Compleat Enchanter by L. Sprague de Camp and Fletcher Pratt is a compilation of the first three novellas in the Harold Shea/Enchanter series, “The Roaring Trumpet” (1940), “The Mathematics of Magic” (1940), and “The Castle of Iron” (1941, revised 1950). The Compleat Enchanter was first published as a Nelson Doubleday/Science Fiction Book Club hardcover in 1975 before being released as a Del Rey paperback in 1976, featuring a charming Brothers Hildebrandt cover painting.

The three adventures in this book take place in the worlds of Norse Mythology, Edmund Spenser’s epic poem The Faerie Queene, and Ludovico Ariosto’s epic poem Orlando Furioso.

De Camp and Pratt would later team up for two more Harold Shea stories, “The Wall of Serpents” (1953), and “The Green Magician” (1954). These stories fall outside of the Appendix N Book Club reading list since they were not collected in paperback until 1979, but Gary Gygax and Tim Kask must have been big fans since “The Green Magician” made its first reappearance in print since 1960 in issues 15 and 16 of The Dragon (1978)!

In any case, the Harold Shea series undoubtedly left its mark on Advanced Dungeons & Dragons, most obviously in the magical spell component requirements in The Players Handbook and the Against the Giants series of modules.
