America Not Discovered by Columbus by Rasmus Anderson

An overview of the question of pre-Columbian explorations of North America, focusing on the idea that Norse explorers beat Columbus to the New World by several centuries, by the incomparable 19th and early 20th century scholar Rasmus B. Anderson. This is not a simple scan, but a completely re-done version of the second (1891) edition, carefully edited and laid out to make the text more accessible to modern audiences.
This volume also includes Paul Barron Watson's comprehensive (as of 1891) bibliography of all the various mentions on the subject in books and periodicals, not limited to the question of the Norse discovery of America, but also the Chinese, Welsh, Arabs, and others.
