Also an argument to consider is that if everyone was using copyright to get the "monopoly" (okay, not the right term) of having something available on a printed book, there would be no web page and no web at all! All the information available for free on the web is a proof that copyright-protected and sold-for-money books are not strictly necessary to encourage creation. However as you said, there is a balance to be found there, see Tim O'Reilly opinions on book publishing on the matter for example. --LG
