How to add an ISSN to existing references
When migrating my personal library from Mendeley to Zotero I lost the ISSNs of my references published in academic journals. How to search for them automatically without having to do that piece by piece, since I have a little more than 10,000 references at the moment? Thank you very much for your help.
As I mentioned to you elsewhere, we'd really recommend using the dedicated migration strategy for getting your data from Mendeley into Zotero rather than relying on the lossy export/import strategy you used.
