I love this book.
It is a beautiful, inspirational compilation of information chock full of grainy b&w photographs of experimental papercrete and paper adobe structures, mixers, etc. There are valuable recipies, speculations, instructions, and considerations, all from guys who have been making stuff out of paper trash, sand, and cement or clay for years now .
Well worth the $32 plus shipping I paid for it.
I've seen used editions of this book on Amazon.com for as much $120.
But your brand new copy is a mere $32 plus shipping at http://papercretenm.com/.
