how to join audiobook tracks in iTunes 11
Since there's no Advanced tab in iTunes 11, I can't figure out how to join audiobook tracks into one. I am trying to add an audiobook to iTunes so I can transfer it to my iPod. For instance, each Disc has 10 different tracks. I used to be able to click on the Advanced tab and then click Join and the tracks would be combined into one. I don't see any option for doing that now. Thanks for any help.
