I've been doing this for the last eight years with pencil, paper, filing cabinets, and archive-boxes. It's reliable, flexible, and easy. However, it's not sustainable in the long run. I currently have five filing cabinets of notes and around a dozen boxes. Most of my colleagues have been at this longer. Their offices (at home and work) are crammed with cardboard boxes and cabinets of well-organized notes. I'd love a technical solution, but I haven't found anything that works for me.
