Let me see if I understand you correctly, you have three routers, one in
area 0 and area 1 (ABR), one in area 1 and area 4 with a VL to area 0, and
one just in area 4 with a VL to the ABR in area 1? And your question is
why can't you see area 4 info on the area 0 router? Well it's because that
router isn't in area 4. If you have an ABR in area 4 then it will have two
seperate link state area databases one for area 0 and one for area 4,
however your ABR in area 0 will have just link state databases for area 0
and area 1. You cannot have an LS database for an area you aren't a member
of, you can have summary LSAs of course or external LSAs that originate for
a different area, but you cannot have area-scope (router and network) LSAs.

Why not just use show ip ospf database <router or network or
external>? That will show you what router is claiming what. I cannot see
why it would be advantageous to see an LSA coming in and to read it right
then, I believe the show ip ospf database will tell you the age of the LSA
anyway so you'll know when it showed up.
