"Ford Model A Standard Hardware", "Parts Price List", and "Body Parts List" books

[28 Special Coupe]

I'm slowly trying to build up my reference library of Model A books and I'm curious about the books sold by the usual vendors called "Ford Model A Standard Hardware", "Parts Price List", and "Body Parts List". What exactly is in them, and are any of them worth having? Do any of them have diagrams or are they just lists of parts? Are there other references you would recommend instead of these? Thanks for your help.
