In reply to Elsier: I wouldn't bother with either the 2011 OAC update or with Morocco Rock - both have been superseded by the new OAC 2013 'Tafraout' guide. Morocco Rock still only covers the North side, with ~1000 routes (compared to the 650 plus 150 you'd get from Anti-Atlas North plus its supplement). In fact, I see that Morocco Rock is being sold off cheaply now it's become obsolete.
The 2013 Tafraout guide has 2000 routes and covers the North and South sides, as well as the granite, so it does the whole area in one. Of these, about 1200 are North side routes - so it's a significant increase on the predecessors even if you only want this side.
A good overview of all the guidebooks currently available is here:
