kyteflyer, I never said I thought that was the only way or that it related to Marvin. I was responding to Paul's allegation that (paraphrasing) "saving books to disk in Calibre is necessary in order to load them with iTunes
" (see Paul's exact quote above). I've just demonstrated this is not true for iBooks, and those of you who use iTunes to manage your iPads might want to check what happens when you drag & drop an EPUB file from a Calibre folder over, say, Marvin's files window. My guess is it will be accepted normally.
