I don't know how this is possible, but there seems to be huge numbers of orthopaedic textbooks converted to PDF files or windows help files. I've seen almost all of the Master Techniques, Skeletal Trauma, Campbell's, Rockwood and Green, Lovell and Winter, Hoppenfeld, Green's Hand etc. It's unbelievable. It's obviously akin to illegally downloading things off Kazaa but it's out there if, say, you already own the book and want a PDF copy of it....uh...say. It sure makes you think about forking over a grand or whatever for Campbell's when you can download it in five minutes.
