437 books, released for free public online access, by University of California Press, following, as Peter Suber notes, the pioneering lead of the National Academy Press, though while the latter is in PDF, the University of California Press is in HTML and hence is much easier to read online. The site also provides linking assistance and a spreadsheet. Outstanding. Other sites hosting free online books include E-Editions - University of Nebraska Press, Baen Books, Hoover Institution, and, of course, Project Gutenberg.
