Thanks, G,

Minded to try this. Seems simpler (and faster) to have Calibre upload books straight to the iBooks app on my iPad. And i Don't really need copies of my books in iTunes since Calibre can function as a backup if needed. But there's the rub :

I have a very large library on my iPad, over 1 200 titles. I like using cover view and have sorted the titles according to author in that view. I think iTunes backs up the layout in cover view (i e which books go where). but does Calibre do the same ? Or will I have to re-sort the whole shebang if I ever have to restore the contents in iBooks ? (Done that once due to error when installing an iTunes upgrade. Never again !)

Thanks once again for your helpful responses.
