I am trying to figure out the best way to keep track of my collection so I don't keep buying duplicates at the convention. Bringing my collection is not a possibility since it takes up way too much room. I don't have the time to continously catalog each chip that I recieve. The more common chips I mark off in my price guides to indicate that I have them. The problem is with the unknown illegal club chips and chips from areas that don't have guides. I have been scanning the pages and printing them in color but that is getting real expensive. I thought about getting a notebook computer and just loading the scans into it but it still takes hours to do the scanning. Does anyone have a better idea? How do you keep track of your collection?
