Thank you so much! I've had 3 readers over the last several years: first a 505 sony (now defunct), replaced by an ipad last year. However, since I find reading on the ipad at night difficult, I just purchased a new kindle 3 this week.
I installed Calibre, and couldn't believe what I'd been missing all these years - it is by far the best library software I've ever had. It's excellent! And it is great to have just one unified ebook library.
