Archetype selection questions

• Does the reader need to act or understand?
• Is the author’s advantage experience, evidence, story or framework?
• How much original research is available?
• Is the book expected to date quickly?
• Does it need extensive citations?
• Is the intended reader a practitioner, buyer, public audience, family or student?
• Does the author need a comprehensive reference or a sharp point of view?

PocketAuthor can use those answers to recommend a structure.
