The Noguchi Filing System

Link: The Noguchi Filing System is a way to organize the paper in your life without requiring that you categorize it. Basically you use “pockets” to hold everything and place them vertically on a shelf. Whenever you need something from a pocket, you remove it from it’s place and place it back on the shelf as the leftmost pocket. This means that over time all of your frequently used pockets will be on the left and the least used pockets will be on the right.

This probably won’t work for everyone, but it can be an interesting way to organize information so it is automatically sorted based roughly on the propability that you will need to view it.
