JS-Script for Zotero to check consistency for your book chapters in your library

check-consistency-book-chapters.js

/*
  Check data consistency for book chapters of the same book
  (isbn check for that). For each outputed object the bookTitle,
  publisher and place should be the same also when there are more
  than one chapter in your currently selected library. If not, then
  you may want to look closer to this reported incosistency. [License: CC0]
