I have read about 15 books on soap making. I have found the 2 following books to have the best info.
Country Living Handmade Soap
ISBN:0-688-15568-6
Making Transparent Soap By Catherine Failor
ISBN:1-58017-244-x
If you are looking melt & pour recipes you should check out...
300 Handcrafted soaps by Marie Browning
ISBN:0-8069-6863-x
This book also has info on how to convert the recipes if you want to hand-mill instead of using melt & Pour.
Hope that helps you out.
FYI. I have check all the above books out and the library and got the info I needed.
