Every library is governed by a series of codes that draw a portrait of their owners. Jesus Marchamalo goes through the libraries of some twenty authors and shows us his obsessions and secret manias. Marguerite Yourcenar said that the best way to meet a person is to see their books. In the case of writers, to know their libraries, their readings, acquires the additional interest to explain their literary universe. Jesus Marchamalo - the library inspector, he was baptized with correct poetry Antonio Gamoneda - has spent years visiting and inspecting libraries of writers. In 2011 published in Siruela a first book dedicated to this subject, where the books are kept, and now presents this new installment of suggestive title, The kingdoms of paper. A tour of the personal libraries of some twenty authors to whom we approach through those small details that mark their relationship with books: the dog Lola, by Elvira Lindo, who adopted a book by Caravaggio; the monastic cell in which he has finished converting his library Manuel Vicent; the photographs of artists of the golden Hollywood that dot the shelves of Marta Sanz; the book that Ezra Pound dedicated, sullen and ill-humored, to Antonio Colinas ... Each of the libraries containing The paper kingdoms draws an original portrait, sometimes unexpected, of its owner, while revealing those prodigious stories that keep inside the books.
