NOTE: A few eTextbooks currently do not have multi-level zoom capability or multiple viewing options in the new Reader. We’re working hard to make these features available for these titles as soon as possible, so if you’re having trouble using multi-level zoom or multiple viewing options, check back again soon. All other features of the new Reader are still available.
