These are the same issues with variant covers:
https://www.comicogs.com/credit/26727-ernie-chua-ernie-chan (used the last name Chua for a period of time)
https://www.comicogs.com/series/93398-detective-comics-1937 (incorrect series name)
https://www.comicogs.com/series/8874-detective-comics (merge into this one)
As discussed in the other merging thread, we prefer to keep variants separate.
With regards to Ernie Chan/Ernie Chua - wondering if this should be treated as an alias rather than merging? We've just updated the guidelines on Bookogs to include this for credits, might apply here too: https://www.bookogs.com/wiki/bookogs-rules-and-guidelines#names
oh and merged those Detective Comics dupes - thanks!
Got it, thanks!
https://www.comicogs.com/credit/7684-jan-duursema-mandrake (updated name change)
https://www.comicogs.com/credit/98400-jan-duuresma (incorrect sp)
https://www.comicogs.com/credit/5249-al-milgrom (he seemed to go by Al more often)
https://www.comicogs.com/credit/6947-artie-simek (again seems to go by Artie more often)
https://www.comicogs.com/series/39452-worlds-finest (incomplete info)
https://www.comicogs.com/series/20329-worlds-finest-comics (updated w/ image, link, etc)
https://www.comicogs.com/series/57406-phantom-stranger-co-starring-deadman (not sure what this is)
https://www.comicogs.com/series/68662-phantom-stranger (I updated this category to include image, notes, link for the series)
Sorry for the mix up:
this is the one that should be used:
merge the other 2 above or delete, there are no issues listed in them.
