Also if you have your books on a SD card you can just pull the SD card out and THEN do the hard reset and the books on the SD card will stay.
I don't think the SD card will get erased even if it is still stuck in the device. But it is a good idea to pop it out.. Less stuff for the device to process at one time when you reset it.
