How Do You Know if You Have a Library on Your Kindle?

A physical book, you remember what you read more effectively. You don't actually own the books that are on your kindle even though you were paying for them. Books are much more permanent. They're going to be a round a lot longer. And then the third reason i would say is, to me, collecting a library isn't just about you. It's about posterity too. I can hand my library down to my kids some day, and they can build on and enhance it even more. That there is something with physical books that speak of you.
