thanks hucairz ! i'm definitely going to take a look at that. it will be nice to have the same book on my phone as on my liseuse ! right now i'm limited to the ones on that website, so it's Moby Dick in the métro and (currently) Anna Katharine Green at home or in the café.
not that i mind reading Moby Dick, mind you.
i do recommend the booksinmyphone.com site also though ; despite the limitations, i think their books are quite well made : you can choose from 3 different font sizes, switch from black on white to white on black, it remembers what page you stopped reading on, automatically suspends if someone calls you, and there are markers which indicate your approximate location in the chapter (on the side, vertically) and in the book (on the bottom, horizontally). and they have a decent selection of classics.
