How "One Hundred Years of Solitude" became a classic

In 1967, Sudamericana Press published One Hundred Years of Solitude (Cien años de soledad), a novel written by a little known Colombian author named Gabriel García Márquez. Neither the writer nor the publisher expected much of the book. They knew, as the publishing giant Alfred A. Knopf once put it, that “many a novel is dead the day it is published.” Unexpectedly, One Hundred Years of Solitude went on to sell over 45 million copies, solidified its stature as a literary classic, and garnered García Márquez fame and acclaim as one of the greatest Spanish-language writers in history.

In 1965, the Argentine Sudamericana Press was a leading publisher of contemporary Latin American literature. Its acquisitions editor, in search of new talent, cold-called García Márquez to publish some of his work. The writer replied with enthusiasm that he was working on One Hundred Years of Solitude, “a very long and very complex novel in which I have placed my best illusions.” Two and a half months before the novel’s release in 1967, García Márquez’s enthusiasm turned into fear. After mistaking an episode of nervous arrhythmia for a heart attack, he confessed in a letter to a friend, “I am very scared.” What troubled him was the fate of his novel; he knew it could die upon its release. His fear was based on a harsh reality of the publishing industry for rising authors: poor sales. García Márquez’s previous four books had sold fewer than 2,500 copies in total.

William Kennedy wrote for the National Observer that it is “the first piece of literature since the Book of Genesis that should be required reading for the entire human race.”
