delete digital booklet from iphone

So deleting the annoying digital booklets... these take up too much space on my iPhone. I bought the latest Coldplay album and the digital booklet automatically synced to my iPhone (rrrrrrr!) taking up a lot of space on my iPhone. I finally figured out how to view the booklet in iBooks and subsequently deleted it from iBooks. However, when managing my iPhone in iTunes and when looking at the usage in my iPhone settings, the book is still there taking up memory. How do I completely delete/remove this from my iPhone and keep it off? So annoying!! Thanks!
