2022 calling! Thanks to the past. Still works with current Calibre. - Strange that Calibre would import 'books' that are available in 0 formats. It where just name of author & title and the cover art.

Clarification;I did not use the script. I mean; go to the search box in Calibre. Click on the configuration icon.And search there to formats:false. Then you have the selection of all empty books. Verify some to see the are indeed empty. ctrl+A to select all. And then 'remove books'. - This works fast even with a large database. No need to use manual commands.

It seems it's possible to create an "empty" book in calibre, and then add files to it later. So that would probably why this happens.
