In reply to humptydumpty:
I liked the ones in the costa blanca guidebook that told you how, why and where to get slightly better guidebooks...
Think it depends, as from a selling guidebook perspective it's quite an expensive game for something that will actually go out of date quite quickly, I think anything that subsidises that cost is probably a good thing. Some guidebooks excepted that need to be subsidised because they aren't very good in the first place.
