Need someone more familiar with untranslated Japanese manga

Hello,

Someone has made a real mess of Yotsuba&! volume 14:

https://www.librarything.com/work/36711485/editions/

I could probably strip out the things that are recognizably Yotsuba volumes and put them in their proper places, but that leaves what looks like dozens of other unrelated works, by multiple different authors. I see some works in there with seemingly-identical titles but different ISBNs attached to them. Same work? Dunno! This is beyond my abilities.

I don't even understand how this could happen, incidentally. Unless there's some method I'm not aware of, you can't mass-combine except within an author's own works, so someone would've had to manually add all of these to their workbench??

ooof. there's a bunch of Yotsuba&! 13 mixed in there, too.

Vivaldi offered to translate the page for me, and I think i saw a dozen titles, lots of multiples, which supports your thought about isbns. I think it may have been a workbench mistake, yeah. :(
