This causes a large gray area in Google Books. There are large number of books still under extended copyright, but no copyright owner can be found. Google has been to court several times by opponents who also want to make money off of distributing grey books. One part of me wants to see 100% of the world&#x27;s books online, not the 15% or so now.  Another part of me wants to be done in as a finacially fair way as possible.
