Is it possible to tell which library a citation has been inserted from?
I understand that Zotero can't handle citations from multiple libraries in one Word document. If, however, this has already happened in a massive, collaboratively edited document, is there an easy-ish way to tell which libraries the citations were pulled from (instead of going through the libraries to check)? Or just to see which references are from different libraries (even if you couldn't tell which library they were from)? If this can't be done precisely, are there any rules of thumb that would help (like, looking for embedded reference identifiers that aren't in the same range as the others)?
