How many Kindle books do you have? KU and Libby books

Remember those email lists that had lists of all the Kindle books currently free or $1.99? They were sorted by genre so it was easy to poke around and there was a new email everyday with different books.

If the book looked at all interesting and it was free, I got it. I told myself, if I was ever stranded alone anywhere, I needed all the books. I guess I planned to be there a LONG time!

So now I have 8,000 purchased books! But I also have Kindle Unlimited AND 3 library cards.

Am I weird? How many books have you purchased and do you also use KU and Libby?
