References are given to the location of the more important documents, so far as these are available in the various collections of printed documents. The value of these sources has been discussed in the preceding pages, and these opinions are not repeated in this list. The titles of the printed books are quoted from the editions which came nearest to the authors’ manuscripts, so far as these editions could be consulted. Reference is made also to the most available later editions, and to the English and French translations of Spanish, Italian, and Latin works. With hardly an exception, the titles are quoted from the volumes themselves, as they were found in the Harvard College Library or in the John Carter Brown Library of Providence. The Lenox Library of New York supplied such volumes as were not to be found in Cambridge, Boston, or Providence. Dr Justin Winsor and Mr F.W. Hodge have rendered very material assistance in giving this list such completeness as it possesses. To Mr Hodge especially are due many of the titles which relate to the ethnological and archeological aspects of the subject. Abelin, Johann Phillip; _pseud._ Johann Ludwig Gottfriedt.
