Legally you are probably right. In a strict sense. But this is probably an area where you'd argue that the text is more of a label than anything under fair use in the same sense I can sell you my review of the book and mention the title as many times as I want. Will that hold up in court? Dunno, I very much doubt anyone cares to challenge it since this sort of thing basically doesn't hurt anyone's profit margins. Unless they are going around competing directly with a hardcorver release or something.
