In reply to Nick Russell:
If you have Morocco Rock and download and print the latest update from their website (£5) you'll have all the crags and routes in "The North" so should only need either the definitive or pocket select from Oxford Alpine for the Ameln Valley in the South. As Mike has pointed out, at least the pocket one can be bought in Tafraout.
Or I can lend you mine (the definitive one) for the price of postage (both ways) if you think there's time to get it to you.
Better still just go climbing in Ameln Valley with the original Claude Davies guide - guaranteed adventure!
Have a great trip.
