R.L. Stine (Goosebumps et. al.)

I was looking at the author page for R. L. Stine and found things that seem to need combining.
I speak/read English only and don't have the time/inclination to check thoroughly enough to fix ...

https://www.librarything.com/nseries/250176/G%C4%99sia-sk%C3%B3rka and https://www.librarything.com/nseries/250180/G%C4%99%C5%9Bia-sk%C3%B3rka appear to be single Goosebumps books translated to Polish such that both series should be combined and merged while the books get combined

Chair de poule , Tome 04: Prisonniers du miroir ... and a dozen titles starting similarly seem to be French translations that should be combined

I also noticed a 'Spanish Edition' and an 'Icelandic Edition' before deciding it was too much for me to focus on.

The Polish books look like double issues. For example, the book in https://www.librarything.com/nseries/250176/G%C4%99sia-sk%C3%B3rka probably contains The Girl Who Cried Monster and Night of the Living Dummy

But yes, the Polish series can certainly be combined. Translations found on the author page need to join their respective works as well. I'm not a Goosebumps specialist, but I'll be happy to help (especially for the French books).
