A clever way to mark one's books, reportedly used by Sir Isaac Newton himself: dog-ear pages so that the tips of folded-in corners point precisely to the important sections of the text. Interestingly enough this is almost always possible, at least for books that aren't too tall and narrow. Drawback: with modern cheap paper the creases may deteriorate and crack after several years. Don't do this to other people's books!
