Please bear with me as I am totally new to both itunes and the ipad. I drag and drop ebooks from my PC to itunes and then sync with my ipad and the books appear in ibooks. If i delete them from ibooks after reading them (because they are saved on my PC) and then sync again, they reappear because they are still in itunes. If I clear out itunes and just try to add a few new books to the ipad it deletes all of the other books that were in still in ibooks. My question then, is there any way (other than going to itunes and removing each individual book that I removed from my ipad) to add three or four books to the ipad without disturbing the changes i have made to ibooks on the ipad? In other words, can I set it up so that itunes adds books, but makes no other changes, or, failing that, Is there a different method to add books to my ipad? It is not jailbroken and I don't consider myself tech savvy enough that I would even try. Thank you for any help you can give.
