The Casover method
Record the route before opening accounts.
The metadata and production step produces a Route Decision Record and controlled Metadata Master. It covers the chosen formats and platforms, ISBN and imprint decisions, descriptions, categories, keywords, prices, Author Central preparation, production files, proofs and release approvals. You approve every live publication action.
Billy MacLeod’s route is deliberately hybrid.
A Sapper’s Story uses KDP for Kindle and paperback, IngramSpark for an ordinary retail hardback, and a separate specialist printer for the premium signed edition. His existing Royal Engineers audience made direct pre-orders and the higher-specification hardback commercially relevant; it is an example, not a default prescription.
Platform features and terms change. Always check the current Amazon KDP, IngramSpark, Draft2Digital and Bookvault guidance at the point of decision.
