Some German paperback publishers credit their main program as "Allgemeine Reihe" (General series), should the credit contain the name of the publishing house respectively the imprint (https://books.discogs.com/credit/21184-heyne-allgemeine-reihe) to avoid various counted credits (https://books.discogs.com/credit/509108-allgemeine-reihe-2), although this is not the way it is shown on the items? Or would we prefer a suffix like "Allgemeine Reihe (Heyne)"?

Yes, i think this is the right way. There are also several German publishers who credit like this in the colophone or title series like that. I think we should stay close to German naming conventions here, so i prefer Heyne Allgemeine Reihe as the correct title.
I also think that naming it Allgemeine Reihe (Heyne) would complicate searching. People will search for Heyne, not for Allgemeine Reihe. I also predict that there will be a lot more of "Allgemeine Reihen"(German plural) in the future.
If more people agree with that, it should be stated clearly in the Wiki. I think it makes sense, to create a language-specific section for this and similar cases. Someone should place a warning sign ( Example ) for unspecific credits like "Allgemeine Reihe" to prevent people from doing the wrong thing again.
