Now that I'm starting to feel better, I've organized a little, cleaned up a little.
You ask what book? I have a book (binder) that has my Copic color charts, Distress Ink swatch page, etc. It has scanned copies of all my stamp sets with names and manufacturer. That way, when I need a stamp set or looking for something particular, I take out my binder and can look to see what I have instead of going through each stamp set. It works well for me.
