The Book of Fantasy contains 79 stories and poems from many sources. Originally published nearly 50 years ago in Argentina, updated in 1965, and available in English for the first time, this collection is based entirely on the editors' preferences, with contents ranging from light fantasy to grim horror.

In addition to stories by Ballard, Poe, Saki, Max Beerbohm, Ray Bradbury, May Sinclair, de Maupassant and Julio Cortazar, there are shorter pieces, anecdotes, folkloric fragments, dreamlike moments. Most of the 79 selections are only a paragraph or two long, giving us brief passage into magical visions of the world culled from the work of an international array of authors of the past three centuries from locales as diverse as South America and ancient China, including less well-known authors such as Santiago Dabove, Edwin Morgan and Niu Chiao. The keynote tale may well be Borges's own "Tlon, Uqbar, Orbis Tertius" in which an imaginary world, conjured up by manufactured documentation, ends up eroding our reality: reality is malleable, and imagination necessarily subverts and alters it.
