There is no way to fix this directly without a backup of the database. But, you don't need to do a factory reset. Signing out of the Kobo account on the device will create a new database when you sign in. This will then reload all the sideloaded books. You will lose the reading status and collections for these books. When you connect to calibre, the collections should be recreated.

Thank you very much for this information Davidfor. About the first part: I do always properly the "Safely remove hardware and Eject Media" procedure so I doubt if that could be the cause. What did happen, and perhaps that plays a role, is the fact that when I tried to refuel the batteries and got the "connect" option I also saw no evidence at all that the Reader was actually charging so I went to another electrical socket in the room to try again. I had the distinct memory that at the first time I charged the battery it did show the percentage of power that was left in the Reader. This time, after looking a lot for it I relaized that I needed to tick the little worm on the top right to get that information. But that aside.
Given the fact that my wife has been using the Reader without any problems at all for about 10 days since I worked on it so succesfully with Calibre also seems to indicate that this was something that went radically wrong in the charging procedure.
Could you please tell me how to sign in and out of the Kobo account?
And please keep in mind, I do NOT have the little home symbol that one normally sees at the left top of the screen available to me.
At the other hand, I am now being confronted with an entirely different screen than I am used to. Left top there is now the word Home in Italics, and when I select it I get a long list (Home, My books, My collections, My articles, Browse, Recommended, Kobo Plus, Wishlist, Activity, Settings, Help) I do remember someone's response that he had a different home screen and perhaps even mentioning that mine was an older version of it.
Can it be that somehow the Reader revised it's own software? Because now that aspect seems to work again while the only thing I did was attach it to my computer to check what's wrong with it. I didn't make any alterations but they seem to have been made....
PS: after safely removing the Reader from my computer and bringing it back to my wife, of course the first thing that showed was the entirely different home screen from what it was before. But more importantly, the Reader now does show the proper books that were on it before the malheur took place!!! One BIG difference: all books have the indicator "unread" while my wife had read several of them and was in the middle of reading a fourth book. So that information (not important but worth noticing) seems to have been lost permanently.
I just saw an episode of the series "Catweazle" that was shown in memory of Geoffrey Bayldon who died a little over 2 weeks ago. Perhaps you'll understand that somehow I do get some similar feelings to the main character of this series when looking at our Reader.... ;-)
Anyhow, having this new way of going "home" and the reappearance of the books that initially seemed erased (and appearance of a few books that had been erased that now are invisible again!) seems to indicate that perhaps things are alright now. I guess I was in the middle of something that was created (new Kobo software?) during the recharging process and that perhaps got finished while the Reader was attached to my computer. Guesses, guesses, I have no idea if these things are true. I put the phrases in Italics above after I realized that they no longer were valid because of the discoveries I made while writing this. Sorry if it looks a bit chaotic that way.
