The various yellow and white pages organizations deliver a whopping 540 million unsolicited books every year, and web site YellowPagesGoesGreen aims to prevent this gigantic and obsolete waste of paper from landing at your doorstep. There is no national service similar to the previously mentioned Do Not Call Registry for opting out of the yellow pages, but most individual yellow and white page organizations claim that you can opt out. What YellowPagesGoesGreen does is provide a centralized location for requesting that all such services in your area stop delivering the books to your doorstep. Because it's not a national registry like Do Not Call, publishers may not be as eager to follow up on your request, but it's worth a try. If you've used this service, let's hear how it worked for you in the comments.
