(1899). Prior to his death, he offered his personal library collection to the National Library of Chile (Biblioteca Nacional de Chile), which contained 30,000 rare books and 500 volumes of documents dated prior to the independence of Latin American nations. Exhaustive study of Magellan In 1920, the Chilean historian published a comprehensive study of Magellan containing an impressive amount of biographical information, a detailed analysis of the beginning and development of the voyage of circumnavigation, and a remarkable amount of information on the crews of the Armada de Molucca. This contained a priceless list of documentary sources and an outstanding bibliography. The title of this work is El Descubrimiento del Oceano Pacifico: Vasco Nuñez, Balboa, Hernando de Magallanes y Sus Compañeros. In the words of Tim Joyner, "Any serious study of Magellan and his enterprise must include this informative product of Medina's exhaustive archival research." In addition, Medina produced the fullest bibliographies yet attainable of books printed at Lima, Mexico and Manila, and a number of memoirs and other minor writings. No other man had rendered anything like the same amount of service to the literary history and bibliography of the Spanish colonies. Medina was designated "Humanist of the Americas" by members of the Pan American Union. Additional works He was recognized as the author, editor, and translator of approximately 282 titles (books, pamphlets, and articles). If additional works like re-editions, sections of books, pre-prints and re-prints of complete or partial works, as well posthumous studies, are included, the total number of publications exceeds 350.
