I have two issues which are probably linked re iBooks.
Firstly, iBook on my iPad (vers 7.0.2) downloads multiple copies (8) of a number of books even after I deleted the copies. Secondly, the books tagged "new" cannot be opened. I turned off Books "automatic downloads" under iTunes & Apps Store but it still downloads the copies.
iMac (21.5-inch, Late 2012), OS X Mountain Lion (10.8.5)
