Thank you. It turns out you cannot drag and drop directly onto the iPad for ebook, tey have to be in iTunes first and then transferred. When I took that extra step, it all worked. I appreciate the comic book recs. I am not sure I want to spend $8 but we'll see
The app store is a bit of a mess, isn't it? It used to have sub-categories so you could browse the whole thing (e.g. apps---games---board games) but no longer. It was a pain to try and find things.
