About World of Books

Since 2002, World of Books has been on a mission to offer an affordable, sustainable alternative for bookworms who want to save money and help the planet. We're your go-to place for buying and selling both preloved and new books — because we believe stories deserve second (and third, and fourth…) chances. With millions of affordable, high-quality titles, we help people read more and waste less.We also love giving books a fresh lease of life through our World of Books - Sell Your Books platform, where anyone can trade in their unwanted reads for cash. It’s simple, sustainable, and keeps books moving from one reader to the next — just the way we like it.And it doesn’t stop there. Through our World of Books - Sell Your Book Pro brand, we work with charities to buy their excess stock in bulk. That means more money for great causes, less waste heading to landfill, and even more books back in circulation.As a proud Certified B Corp, we don’t just talk the talk. We’re working to become the world’s most sustainable online bookstore — measuring success by the good we do for the planet, the people we support, and the stories we help keep alive.
