Hi Sarah, Are you currently registered as a volunteer? If so, you can validate books. If you're not a volunteer yet, the first step is to sign up to be one. If you need to do that, you can write to support@xxxxxxxxxxxxx and ask John Glass what you need to do to get signed up. If you're already a volunteer, tell us and we can give instructions for validating. Many of us really enjoy validating, and I hope you will too. Kellie
