I served my time with the standard collection of three-hole ring binders and got into the standard mess of loose (torn ring-hole) sheets.
This was pre-computer of course. Why does everyone go to such lenghths to preserve what is instantly replaceable with new at the cost of a couple of seconds printing?
I have found that there is available an assortment of plactic folders that will hold around three hundred sheets of A4.
I doctor the folders so that the sheets stand upright in them, with the top edges clear so that they can be riffled through, and as they are loose sheets they can be kept alphabetical with no trouble at all.
