I've looked through a box of owner's manuals to find instructions for a small item to list on eBay; in the process I've found a handful of manuals for items I no longer own.

As a personal hobby, I enjoy looking through the sites like http://www.manualsonline.com/ and if I have one that isn't listed, I scan and add it. This helps other people like me who have items they want to sell find out information and print it up to include in the shipping box. Or people like me who buy used appliances and want to know how they work, etc. So that stack of manuals will be slowly scanned and entered into the site then tossed into the recycle bin. (You used to be able to find such manuals on eBay, but people always charged too much for them, and this online sharing of manuals is a much better way of operating.)

I didn't find the booklet I was looking for, but I found them for a couple of other things that are around here that should also go on eBay, so those are in a different stack.
