Yes! I have some books I really recomend!
For pure and Natural soaps I recommend these books.
Soap Recipes, by Elaine White, making modern soap with herbs beeswax and vegetable oils.
Country Living Handmade soap, by Mike Hulbert.
The Handmade Soap Book, by Melinda Coss.
Making Scented Soap, by Linda Hamblen.
A few of these books have melt and pour recipes as well. You can get most of them through the library.
