Berkowitz: Building Service Provider Networks (Wiley)
Greene and Smith: Cisco ISP Essentials (Cisco Press)

Having given those references, ISIS is more common than OSPF as an 
ISP IGP.  I have seen good designs with OSPF, generally where there 
were lots of servers in the ISP or there were other needs for 
finer-grained route propagation than is typical in ISIS.

To clarify something in another post, however, an ISP needs _both_ an 
IGP and BGP. Many larger ones will also use (G)MPLS setup.
