The spreadsheet thing is painfully slow, but we made our own, and can include the info that's important to us. It's expandable too, of course. I think we have many many records with nothing to scan, so that feature really doesn't matter much. I imagine though, one could create such a system and print labels, but then it's just double the work. I thought of also including some jacket pics.
We too need an inventory, and I know Anders has some doubles of things he wants to find a home for.
We need to do the same thing for the radios and audio equipment.
