Just find a printing press or a newspaper recycling center. They'll have loads of old newsprint. You can also call one of the area newspapers or any other publication and ask them what they do with their returns and that you're interested in getting some papers for your intended purpose. I can't imagine them not helping out.
Make sure the publisher uses soy-based ink. http://landscaping.about.com/od/compostandmulch/f/newspaper_mulch.htm
Well there's a driveway a few houses down that has quite a collection...:lol: Sorry, just couldn't resist.:jester:
