A few years ago I had published a short article in Woodwork magazine about Paper Sloyd, describing its usefulness, both as a precursor to woodworking and also in the development of skills required for algebra, geometry and trigonometry. I got a number of inquiries about where the book could be found, and to make it available, and as it was no longer covered by copyright protection, I scanned and copied its pages for distribution to interested teachers. Now Google Books has made that book available for free download. Paper Sloyd, by Ednah Anne Rich, 1905.
