I got Lammle's book to study for my resit and to be honest I was surprised at the lack of detail, probably too used to Odom. Stuff that Lammle covers that Odom doesn't: Packet types and neighbour states for EIGRP, OSPF, HSRP, IPv6. (OSPF LSA's aren't on the exam topics). And of course he explains topics from a different perspective. What helped me the most from his material was actually his practice questions and flash cards, his style of question had the sort of vagueness that I struggled with on the Cisco exam.
