the Rolls Royce book is pretty inclusive,
Way back when I did the course there were two reference books recommended.
First was the Rolls Royce book. T' other was the Pratt and Whitney.
The P&W was the cheaper (in purchase) cost of the two. Cannot remember now actually how much, but do remember that the RR one was around $30 more!!
The RR book was considered to be the better of the two.
