You can easily load all of your books onto your new Kindle. Amazon retains a record of all your book purchases in an archive. When you register your new Kindle (and turn on wireless) it 'phones home' to Amazon and Amazon places an entry on your main menu entitled Archive. Just click on that entry and all of your past book purchases will appear and will automatically be downloaded to the Kindle when you click on them.

However, if your old Kindle contained any books, pictures, or documents that you did NOT purchase from Amazon, those items will not appear in the Amazon archive. You will have to download those items to your new Kindle the same way you installed them on the old Kindle. If the only location of those un-archived documents is the old Kindle, then this will become a two step process because you cannot copy from one Kindle directly to another. Instead you must copy the documents off the old Kindle onto a computer using the USB cable, and then copy the books from the computer onto the new Kindle by way of the USB cable or by email using an authorized email account. (To authorize an email account for sending books to your Kindle, please visit Amazon's "manage my devices" section. If the new Kindle is not registered, or if it is blacklisted, then you cannot use the email method to transfer the books. The only way to install books on an unregistered Kindle is directly via USB cable.)
