I noticed the other day that my Sony 950 suddenly had 120 collections, none of which I created and many of which were absurd. So I followed the instructions Sony provides and deleted them. All was fine until yesterday when I used Calibre to add some ebooks to my 950. Afterwards, I noticed I now had 91 new collections.

I checked my preferences in Calibre and note that the collections are set for manual. But reading the description of the 3 choices indicates that Calibre will create collections regardless of which I choose.

Is there a way to permanently prevent Calibre from creating collections?

If not, this would be an option I would like to see in an update.
