The Thurston James book is excellent- I bought it many years ago and I constantly reference it. Everyone should have a copy.
One book that I have is Plastics For Modellers by Alex Weiss. It's a great resource- it shows all types of plastics and what each type is used for, types of cement and glues, molding, casting, etc. Another book is Professional Modelmaking by Norman Trudeau. It's geared more toward designers and architects but it's still a good book.
There was a whole series of books published by Finescale Modeler on dioramas, scratchbuilding, etc. that are very good. Osprey Publishing did a Masterclass series of books that is also excellent.
