In the same website, you may also download the following books:
Doctrina Christiana - The first book ever to be printed in the country in 1593(!). Doctrina was probably second to the Bible in terms of religious importance to the early Filipinos, if not more. The text is available in Spanish, English, and Tagalog.
True Version of the Philippine Revolution - Written by Emilio Aguinaldo himself. Why did he need to publish a book with such a dubious title? This book was dedicated to the Americans, and published just when the Philippine-American War was starting. In it, he defends himself against issues about his conduct as president, justifies our revolution against the Spaniards, and basically tells the US that he wants to be friends. Hmmm.
The Philippine Islands, 1493-1898 - A 55-volume work, compiling notes from some of the earliest Spanish conquistadors that have set foot in the country. The books detail their observations of the people, as well as the changing religious, political, and economic landscape in a span of four centuries. It’s safe to say that only the most determined scholar would read it in its entirety, but isn’t it wonderful to know that it’s out there?
