Change Order of ISBN Lookup?

I dislike Library of Congress ISBN lookup, LOC do not follow the capitalization of the book titles. I modified the engines.json to add AbeBooks and Library Thing. I tried again for ISBN lookup (, it still using LOC for the lookup. Is there a way to change the order of the look up? or disable LOC lookup? I would assumed it is not possible because it didn't give me the option to turn off LOC.
  • I am guessing there is no way to change this behavior?

    Nothing easy, no. You'd have to go pretty far into the code to change it. (edit: and then with reasonable effort you only have the choice to adjust between LoC, Worldcat, and the German GVB; the lookup engines don't do the same as the ISBN importers)

    Note, though, that if you're reason for disliking LoC is the title casing, you should reconsider: https://www.zotero.org/support/kb/sentence_casing
