Use a clear file that is bound together by screws. In this way you can de-screw the clear file leaves and make pockets easily. Once you’re done with the pockets you can just gather them and put the screws on to hold them together. I don’t want to make a step-by-step “how to” here, it’s too easy to do. I know you can already picture-out how to do it. Or, you might also have been doing it already for your bookmarks. I guess it’s the easiest and smartest (and cheapest) way to organize a bookmark collection, right?
I’d love to hear how you keep your bookmark collection. :)
