And there is the catch: at least in the Netherlands, such copying would be legal, under 2 conditions:
- you make the copy yourself
- the copy is for personal use only (study, etc.)
And as far as I know, the same applies to books borrowed from a library... (note that I'm not a lawyer, so use at your own risk)
I know such copying would be illegal in several other countries (France afaik among them). So rules about copyright, "intellectual property" and privacy can differ widely in different jurisdictions.
