Abstract:

If you photocopy an article in the U.S., you apply U.S. copyright law. If you photocopy an article in France, you apply French copyright law. That's the way international copyright law works: You apply the law of the country in which use of the work is made. This is called "national treatment" and is the underlying principle in the leading copyright convention, the Berne Copyright Convention.
