Having a letter which represents a letter for each Era.
E.g.O = Old  M = Modern,  F = football era, N = Near Future.
Then for Books in the Series to Address the problems of denotion between a main book and subsets we could have M = Main Book, N = Novella, Then the final 4 numbers would tell you the sequence on the system cause there's going to be alot of books however to enable books to be added without having to go and renumber things later you could have a spacing of 100 between main books. Scott would have more of an idea of how many sub books there could be in certain situations. But the idea is the numbers is to try and keep the sequence in tact with the letters to provide the era and book type.
The Rookie would be GM0001
The All Pro would be GM0100 

What do people think ?
