I was going thru memphis a long time ago and picked up a book by John Willingham
I think its called Real BBQ or something like that.
If you really need the title I will check it at home and post
It has rubs, marinades, and a bunch of other things, even for you tinkerers it has drawings of a smoker.
I use a bunch of the rubs, and marinades when I smoke, and grill.
Great to have
