Christopher Columbus Copy Book

A manuscript containing the transcription of nine letters apparently sent by Christopher Columbus to the Catholic Monarchs, which appeared in 1985 in Tarragona, is called the Christopher Columbus Copy Book (Spanish: Libro copiador de Cristóbal Colón). From the form of the handwriting it has been estimated that the book could date from the last third of the 16th century. Most of the nine documents are "letter-relations" that narrate the events of Columbus' various voyages of discovery to the Indies; seven were previously unknown and the other two contain a different text from what was already known.

There is no unanimity as to whether the contents of the Copy Book are the work of Columbus, but most historians accept its authenticity. If confirmed as authentic, the discovery of the Copy Book would constitute the most important discovery of documents relating to Columbus' voyages in the 20th century.
