I got the books loaded by sending them to Dropbox from the PC . In Ipad I wwent to Dropbox and downloaded them
The iBook app was mentioned in your first reply. no name for it.
from your post: If so, you can simply sync them to the iPad via iTunes when connected, or download them to the iPad directly vis the iBooks app.
Normally if you purchase books, you use the iBooks app on the iPad. If it is not installed, you can download it directly from the App Store on the iPad. If they were acquired some other way, your solution will work.
