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. http://www.scribd.com/doc/2054609/The-Art-and-Science-of-Dumpster-Diving-by-John-Hoffman
