Thanks for the quick replies!
Here's a couple I remember off the top of my head:
1st Issue Special
is listed twice. Once, correctly, as 1st Issue Special and duplicated as First Issue Special
The Mutant Misadventures of Cloak and Dagger
is listed twice. Once as shown and once as Cloak and Dagger (1989)
. There may have been a title change, but both titles have the same issues listed.
A couple that I haven't sent corrections on:
All-Star Batman and Robin, the Boy Wonder
has two listings.
Creator Sharman DiVono
has two misspelled entries: Sharman DiVorno
and Sharman Divond
