I want to know the answer to the following question:
What directive in 2001 let European Union countries to enact laws that allowed making copies for personal use?
All the background I'm provided with is that "The personal copying exemption in the copyright law of EU member states stems from the EU Copyright Directive of 2001, which is generally devised to allow EU members to enact laws sanctioning making copies without authorization, as long as they are for personal, noncommerical use.". Is that enough to answer the question?
Answer: yes
