Boyago -- Not Lindy, but I'm chiming in anyway. I don't think you're going to find a single reference that will give you all the info you want, especially about how EOs and soap get along with each other.
If I was stranded on a desert island and could only take one EO reference book, I'd choose Essential Oil Safety by Robert Tisserand and Rodney Young. I also respect the information on Tisserand's website http://roberttisserand.com/ and the Nature's Gift website http://www.naturesgift.com/aromatherapytable.htm Aromaweb is worthwhile as a general overview http://aromaweb.com/
I've grown to be skeptical of information from most other authors in the essential oil and aromatherapy field, including Gatefosse, Valnet, Lawless, etc. The supposed properties of various EOs in these books (and many websites) appear to mostly be of the "I read it on the internet or in an older book, so it must be true" variety. I don't see much evidence of original scholarly research being done by most authors in this field. I'm not trying to say there are no nuggets of good information in these books (and websites), but I do find myself having to read them with a skeptical eye.
