If you want to delete books from your Sony Reader, you can do it either by deleting a book derectly from reader, or start up eBook Library, navigate to the Reader and delete the books. Probably you can do via Calibre interface as well, but I don't use it, so I don't know how.
P.S. when I say directly from reader, I mean without connecting it to your PC. Just go to a book's menu. Choose settings, then delete option.
