I figure the fact that they are out of print and you can't buy them anywhere kinda makes the copyright no so big an issue....as long as your not selling it.

I bet TnPShow would host them if you did scan one.

I found photocopying it at work, then putting it on the scanner at home (which has a sheet feeder) was the easiest way.

And use Adobe Acrobat to scan it (the you can do text recognition as well) - which is cool as it makes it searchable.
