  • Look at what has been left behind with a view to adding back any items that you think should be in your Calibre library
This does not explain why your library seems to have got messed up in the first place. Reasons I have come across are:
  • Storing the Calibre library on Cloud based storage. If you ever run Calibre from two locations at the same time or if the sync process interferes with a running instance of Calibre then library corruption can occur.
  • Storing the Calibre library on a network drive. This works a lot of the time but it is not officially supported as things occasionally go wrong.
  • Storing the Calibre library in Google Drive. This can mess up a Calibre library by silently renaming folders with numbers in brackets (as used by Calibre).
  • Any manual manipulation of the files stored in the Calibre library bypassing the Calibre GUI.

Damn, point n3 applies. I keep my Calibre Library inside the Google Drive folder, because 1) I want a constant backup and 2) I read my PDFs on an iPad, and I sync the book I need from Google Drive, do my annotations so that they then are automatically added to the file on my computer. It's strange tho, because I've used this system for years (for about 3 years I was on Sugarsync, then they decided to charge, so I moved to Google Drive about a year ago). Could it be just that?

But again, what mostly concerns me is: were are the 200+ books which now are just missing? if I order my Calibre library for file size I can easily see that I've got over 200 entries without a size. If i click view path some of them will be there (so why doesn't it see them?), but some are missing...
