The Dictionary of Imaginary Places (1980, 1987, 1999) is a book written by Alberto Manguel and Gianni Guadalupi.
Originally published in 1980 and expanded in 1987 and 1999, the Dictionary covers the terrains that readers of literature would expect—Ruritania and Shangri-La, Xanadu and Atlantis, L. Frank Baum's Oz,[1] Lewis Carroll's Wonderland, Thomas More's Utopia, Edwin Abbott's Flatland, C. S. Lewis' Narnia, and the realms of Jonathan Swift and J. R. R. Tolkien; and also a vast host of other venues, created by authors ranging from Dylan Thomas to Cervantes to Edgar Rice Burroughs, from Carl Sandburg to Rabelais to Sir Arthur Conan Doyle.
It compensates by covering a wide range of anonymous and obscure sources, and volumes of forgotten lore.
Guadalupi and Manguel acknowledge Philip Grove's The Imaginary Voyage in Prose Fiction (1941), and Pierre Versins' Encyclopèdie de l'Utopie, des Voyages extraordinaires et de la Science-Fiction (1972), as precedents and inspirations.
The book had an influence on the development of early Japanese role-playing video games at Nihon Falcom.
