I've got a few Definity, AUDIX, Magix and Legend manuals sitting around still in their original shrink wrap. It's especially hard to justify their existance as Avaya continues to host PDF versions on their website.

For telco manuals that I don't already own--plus a few odds and other ends--I sometimes reference the manual bible website". If you go up to the root directory, you'll see that there are other goodies about pinhole cameras, the Atari 2600 and other crazy things.
