Consider other books written by authors of the Latin American Boom, such as Hopscotch by Julio Cortázar and The Death of Artemio Cruz by Carlos Fuentes.
Consider other books by Gabriel García Márquez, such as Love in the Time of Cholera or Strange Pilgrims, his collection of short stories.
It might be interesting to compare One Hundred Years of Solitude to texts by more modern Latin American authors like Distant Star by Roberto Bolano and Invisible Mountain by Carolina De Robertis.
