I’ve zipped and upped a couple of Andrew Loomis' books here, in PDF format, namely:
1) Drawing the Head and the Hands
2) Figure Drawing for All It’s Worth
3) Fun With a Pencil
4) Successful Drawing
His works are out of print and in public domain, so please feel free to share and share alike. His books are dead useful for figure drawing; I’ve learned a lot from them.
