Your college library may have a lot of information. But this is a highly controversial subject. How much should be placed in museums? How can they store it all? How much should be in the hands of private collectors?
I don't feel I violated any ethics by buying two small pieces of plain mosaics that may have come from a Roman street over 1500 years ago.
Where would one go to explore these and other closely related current problems: How should museums and archives work? Should they save everything? Who should have access to what and when?
