We are in the process of designing a nifty new interface for printing and exporting your books -- uniquely created by each person.
In the meantime, I've thrown up an export page with your basic information on it. You can find the link on your My Account page.
You can copy and paste this page into Excel or just save the page itself to your computer. Either way, you will now have a copy of your bookshelf to use as you like.
