I use 5mm A4 squared paper in cheap A4 card folders (pad goes in front of pages torn out which are numbered), I use different colored folders and I have a rule that pad goes in a folder before I get a different pad out, I think in 3 years I've written in the wrong pad one or twice.
The advantage of this approach is that I can jot random crap in a pad and then if it's really not relevant just rip it out and bin it, I only number the top page of the pad that way if I do need to bin it I can just write the same number on the next page.
Having all the pages (neatly) torn out also means I can shove them through the scanner tray on the copiers at work which is nice and of course spread them around my desk, put third party pages in (and number them) etc.
I usually keep the folders for a few months then if I haven't referred to them (I write the last date I did on the back of the folder) I just scan them into decent quality TIFF's and recycle them.
