Legacy books MUST have the identical path they had when you exported their .ris file and imported it into Zotero. Reexport all new .ris files for ALL of your legacy .pdf files.

The linked item in Zotero has the Calibre .pdf in its Zotero Extra field, which is used to match .ris-path books.

If you have moved your Calibre Library directory, then the Extra column is now wrong and will never match Calibre. Linking forces you to NEVER change absolute paths in the future.

That means that your use of Calibre Portable 5.99.8 for ZMI is a very bad idea if your real library is underneath Portable where Calibre always puts it.


My previous post of the Scalzi example proves that Linking via ris and Comparing works properly. The attachment next to it proves that importing from Zotero and then comparing works properly.


I suspect that your real ZMI Calibre Library is not on Calibre 5.99.8, and hence cannot use the latest version of ZMI. So, you cannot have done what I said to do, but rather are running a thought experiment.
