It depends on the country. Guessing from the username, sampo is propably Finnish (like myself) and in Finland you are allowed to make a few private copies of any legally produced and distributed books/media (such as a book borrowed from a library) unless it's protected by an "effective technical protection" (so, if you download a non-DRMed movie from a site where it is legally distributed, you can make private copies). Private copy means a copy used by yourself, your family or close friends.
