.pdf library of old woodworking books

Joe left a link in comments to a site with old woodworking books as .pdf files including Salomon's Teacher's Guide. Evenfalls' Woodworks Library could keep you reading for months. I also recommend Google books. There are a number of titles available there, too. For example, search for "sloyd or slöjd". But there is nothing like holding an original copy in your own hands.
