Another example that comes to mind is Dennis Hopeless. He decided to use Dennis Hallum for Sea of Stars, a creator-owned series at Image. In the CB Writers Search, he comes up as Dennis Hopeless (599 entries), Dennis "Hopeless" Hallum (86 entries of which Sea of Stars shows up), and Dennis Hallum (19 entries). I think this is also a good example of needing to merge a creator's lists together. And the suggestion above is a good one to list aliases for a creator so that no matter how one searches, you find everything by that creator.
Related to this, I'm glad there's been a cleanup of names to make sure they're correct. That's been one of my frustrations trying to find someone's full list when there's misspellings, etc.
