The Labyrinth of Solitude (El laberinto de la soledad)

Chief trap is the 1959 Fondo de Cultura Económica second edition (issued in the "Vida y Pensamiento de México" series): it is substantially revised and expanded — it incorporates the "Nuestros días" material as a full eighth chapter — and is the standard/definitive TEXT most people read and cite, but it is the SECOND edition, not the collectible first. Later FCE printings (Colección Popular and the Lecturas Mexicanas series) are common reading copies. On the English side, the 1961 Grove Press first is the point of issue; later Grove reprints and the 1985 expanded Grove edition, "The Labyrinth of Solitude and Other Writings" (which adds The Other Mexico, Return to the Labyrinth of Solitude, and further essays), are not the first. No prominent U.S. book-club edition of this title is documented in the sources reviewed; the likelier confusion is edition (1950 vs. 1959), not a book-club printing.
