I don't have an iPad, so maybe Apple has changed the way to download archives to your PC, but I think you have to install iTunes in your PC and connect the iPad by cable.
Or maybe you can send yourself an email from the iPad (Google, Microsoft, Yahoo... accounts, I don't know if an Apple email account would be accessible from a PC) and attach to the email the books you want to pass to your PC. If they weren't bought on Apple's iBooks store you'll be able to read them in other devices. If they were bought on iBooks, I think you are out of luck, since if they have DRM you are locked to read them on Apple devices.
