Yesterday, I posted a paste to a PDF download of John Hoffman's book,
"The Art And Science Of Dumpster Diving", but after it pasted, the
link was screwed up!

I think this was because the file name for the PDF had spaces in it.

At any rate, I found another copy on Scribd. You may have to start a 
Scribd account in order to download a copy, but you can at least read
it on the page.
