a Audiobook that shows up in iTunes? I've gone to my Music folder and deleted it from the Audiobooks folder, but it still shows up in iTunes. It was NOT purchased via iTunes but rather I added it myself. Thanks for your help!
I ran into the same problem recently, when I added several audiobooks to iTunes. I noticed that when I didn't use the "add to iTunes automatically" folder, the delete option was grayed out. I manually deleted the folder like you did, and ITunes still showed the book. I deleted the lts and library files and then used the auto add folder. Annoying problem solved.
