The Legality of Lending Books.

In the US, that is handled by the Copyright Act, which says:

Yes. Libraries have a special dispensation that allows them to make archive copies of copyrighted material. They can then circulate the copies. However, this only applies to actual libraries (and the definition of a “library” is strict), not to individuals.

So is it illegal for someone with a photographic memory to remember (copy onto wetware) books, cd, and movies they have experienced? :wink:

In Asia, theres a rather active and thriving pirated, photocopied book trade. In that case, then economics of copying do work out cheaper than buying.

That is a topic for a whole new tirade.
Revised yearly if not quarterly so that the used college text book market is nonexistent.
