Tell us about yourself!
I admit it's not a very good book, but to my knowledge, it's the only one on the subject. To date, I don't think there's another one. It is a bit disjointed. I had to jump back and forth to cobble together some semblance of instructions. I unfortunately do ot have specific temperatures for you. I haven't made liquid soap in years, but it's a similar process to bar soap...to a point. I hope my instructable helps a little.
