I apologize if this has been asked before. I've been searching for quite a while without luck. I probably just don't know what I'm looking for, exactly.

Okay, here we go:

- I have a Sony ereader. I have organized the ebooks on that ereader into dozens of Collections.
- I have tags enabled on Calibre. Obviously, they do not match the collections on my ereader. I end up with dozens of different variations on "sci-fi" or whatever.
- When I add a book from my library to the ereader, calibre takes the tag data from the ebook file on my computer and makes that the collection on the ereader... which I then change on the ereader. Again, if I didn't, I'd have fifty different collections called "Science Fiction" "scifi" "sci-fi" etc.
- I am looking to do the reverse: copy the ebooks from my ereader to my computer library, and have the collection data show up as a tag.
- The reasoning is simple: if my current Sony ereader dies, I want to be able to buy a new one, transfer my library onto it, and not have to enter collection data for everything on the new ereader. I'd like Calibre to have that info already.


How do I go about this, short of entering the data in one book at a time?

To be clear, I am looking for a way to mass copy collection data from the ereader to the calibre library on my computer. I am more than happy to delete my entire computer library and re-copy all of the books back to it from the ereader, if that's what it takes. I just don't know how to get calibre to look at the collection data on the reader, and then enter that info as tag data when the files get copied onto the computer.

Any help would be greatly appreciated!
