I have 126 books. I know because whenever I get a new book I put it on my purchased list on Amazon so that my family will know what I have and not buy me repeats. About a third of them are about quilt history. History of any form has always fascinated me.
I have 20 magazines that I will be keeping. There is about twice that many mags that I still need to go through and copy patterns I am interested in and put them in notebooks. I keep the magazines intact and pass them on. I have three 3" notebooks of patterns that I have decided to keep.
I have an amazon wish list of 391 books. Periodically I go through it and edit.
