A couple of things to note when comparing the OSPF database to the resultant routing table. According to the OSPF specification, an ABR will not install any Network Summary LSAs (LSA type 3s) that it originates into it's routing table. Also, an ABR will only install Network Summary LSAs that are present in the backbone, it will ignore any that are present in non-backbone areas. ASBRs will never install external LSAs that they originate either. Other tricks with external LSAs are that they will only be installed if the route to reach the forwarding address (assuming a non-zero forwarding address) is an intra or inter area route. NSSA external forwarding addresses need to be reachable via intra-area routes. I guess a good thing to ask would be what routes are not being installed, if you could send the database and routing table I hopefully will be able to tell you why.
