I recently came across this book http://www.amazon.com/The-Knowledge-Reb ... 159420523X
More importantly, I came across it's bibliography with links provided where you can get access to the source of information where available here: http://the-knowledge.org/en-gb/bibliography/
I have yet to get it or read it but have already started to access the information in the biblio. Nothing short of a treasure of knowledge here. Oh, yea, that's the name of the book. Almost.
