Q: how can i delete books from ibooks on iMac

Control click a book then click Delete from the pop up menu.

That doesn't work. It only allows you to delete your local copy but keeps the book in your library. The instructions on Apple's site are also incorrect. They suggest going to iTunes and selecting Books from the Library menu, but there is no Books option under that menu in the current version.

Anyone at Apple listening?

I'm also keen to know the answer to this.

So far it only seems possible to delete a local copy. How & where do you remove the book from your account/cloud??
