 Since the 1980s it has become common to speak of "Post-Boom" writers, most of whom were born during the 1940s, 1950s and 1960s, such as Roberto Bolaño, the post-Boom Spanish-language writer who has made the greatest impact on world literature.It is difficult to clearly situate the Post-Boom as many of its writers were active before the end of the Boom.Indeed, some writers, like José Donoso could be said to belong to both movements.
