Do you know when César Vallejo was born? Was he a communist or a lapsed Catholic, or both? Do you know what he died of? Did you know that a new collection of hand-written manuscripts has been recently discovered in Montevideo? You may not know the answer to all these questions (some of them may be unanswerable) but this book will help you to identify and compare the competing answers. It describes and evaluates the manuscripts, editions, books, collections of essays, articles, translations, and doctoral theses written about Vallejo by a wealth of scholars since Vallejo's death on Good Friday 1938.
