I'd definitely contact him and say hey what's up, this has pages missing which while not major (since you say it's just publishers info) I wasn't informed about this.
Generally a decent seller will apologize and offer some compensation for the oversight, but if you're not happy with the reply you can take it a step further through ebay/paypal.
If it gets to that point I would be likely to leave a negative, because while it's not a major damage it's still significantly not as described and if you need to go through the claims system then that's a paddlin'... I mean strike.
