The Philippine Islands, 1493–1898
The Philippine Islands, 1493–1898, often referred to as Blair and Robertson after its two authors, was a 55-volume series of Philippine historical documents. They were translated by Emma Helen Blair and James Alexander Robertson, a director of the National Library of the Philippines from 1910 to 1916.
The original 55-volume set was published from 1903 through 1909 by the Arthur H. Clark Company in Cleveland, Ohio. No more than 500 sets were printed and sold between 1903 and 1909. In 1962, a reissue by photo-offset was printed in Taipeh, limited to 300 sets.
