This is a series of trade paperbacks that according to the indica and the GCD are part of a series. 27 issues/volumes in total.
The CLZ database has most of them as individual trade paperbacks. I say most because some of them didn’t come up with a cursory seach, but they might be in the DB anyway.
I understand but I’m going to leave these like they are seeing they are more easy to find when searching on title. Also, people are always free to create a series for these in their local database of course. Thank you for reporting.
