Author issues

[laven]

I didn't really know where to put this, let me explain. There is this publisher that publishes these little books that you can like gift your friends or family in which are nice phrases that express your love for them.... hopefully you know what I mean
So, these books don't really have an author, they're made by the entire publisher. The problem is, people give this publisher as an author different names. So far, I found 4 different variations:
-Groh
-Groh Verlag (german word for publisher)
-Joachim Groh (probably the name of the founder)
-Groh Kreativteam (german for "creative team")

So... maybe it would be the best to put them all under one name, I'd suggest Groh but idk ??

Left Joachim Groh, listed as editor for a couple; combined the others under Groh. Might need some removed as not books at all; leaving for someone with better language skills.
