Not exactly sure how many I have but over 200 I think.
I gave five large bag fulls to a Charity shop when I moved two years ago but I still have loads, mostly still in bags as I have no bookshelves at the moment.
I don't often buy a new book unless it's a bargain or something I really, really want. I mostly buy in Charity shops.
I've always loved books - you can never have too many!
