With its 1st edition published in 1960 intended for students of the U.P., The History of the Filipino People is still going strong as the de facto history of the Philippines, with its 8th edition. The author's perceived leftist bent brought about several revisions of the book through the years, including a deletion of 3 of its chapters at one time, which is a testament to how book censorship in the country played out. Its now-famous cover was done by Malang, by the way, which makes the book a classic in every sense of the word.
