Deleting books
I want to delete some books I purchased from ibook store. Some I have downloaded to my computer and others I have not. I want to delete the ones off my computer and the ones that are "sitting" in ibook store ready to be downloaded to my computer. Everyone talks about how to hide books which you can then unhide later on if you want them back, but I want to deleted them off of my "purchased" list in the ibook store. How do I do that?
