I have a 16GB Apple iPad 3(with Retina Display). Today, while checking up my available memory, I saw the iPad had about only 1GB left. After deleting major unused apps, I found out that iBooks was using up 1.4GB of storage. I found it to be extremely weird, since iBooks isn't supposed to be consuming so much of space, unless you cram thousands of ebooks in there.
I have only 4 PDFs and 4 books(purchased from the App Store). Each of these books have about a few hundred (max ~600-700) pages. So, I'm not sure how is the 1.4GB being used up by iBooks.
I'd really like to free up the space iBooks seems to be using. Any help would be appreciated.
