There is a particular bolt, called a 'Chicago bolt' that is used to hold papers to a front & back cover. You see them on some albums or books. They go thru the front cover, thru the papers & into the back cover fastening somehow. I was told that they can be purchased in a stationary store. Office Depot told me to go to a home improvement store. I can't find them, under that name or any thing like it, at Lowe's or on the net. Does anyone know what I'm looking for, and possibly by another name?
