This is an archive of books that are, or at some time were, freely accessible on the internet. I tried to select books of "universal value", that is, ones whose contents does not get obsoleted as the time passes. So if you're looking for trendy stuff (C#, Java, XML, etc.), you won't find it here.
Since the stuff on the web tends to disappear or move, I have in some cases also linked to the local copy of the book.
