QUICK ANSWER
Is Your Book Idea Good? The PocketAuthor Book Worthiness Test
A book idea can sound exciting and still be too broad, too derivative, too thin, too weakly sourced or better suited to an article. The right pre-drafting quest
Key takeaways
- 1. Author advantage
- 2. Reader urgency
- 3. Distinctive thesis
- 4. Evidence base
- 5. Intended effect
A book idea can sound exciting and still be too broad, too derivative, too thin, too weakly sourced or better suited to an article. The right pre-drafting question is not “Can I generate enough words?” It is “Does this idea deserve book-length treatment?”
1. Author advantage
Why are you unusually qualified to write this? Strong answers include repeated field experience, unusual access, original research, a distinctive combination of domains, or a documented method developed over time.
2. Reader urgency
Name a reader in a situation, not an audience category. “Managers” is broad. “First-time engineering managers inheriting a team of former peers” is actionable.
3. Distinctive thesis
A topic is not a thesis. “Leadership” is a topic. A thesis is a specific claim that can be supported, challenged and explored.
4. Evidence base
List what supports the project: research, interviews, original data, field experience, public records, documented cases and primary sources. Then identify the gaps.
5. Intended effect
What should be different because this book exists? Better decisions, a shared vocabulary, a documented method, an accessible synthesis or a preserved legacy are all legitimate.
How to score it
Score each dimension from 0–5. A strong concept with available source material may be ready. A weaker concept may be better as an essay, field guide or research project. PocketAuthor is designed to be willing to recommend a shorter format rather than force every idea into a conventional book.
Frequently Asked Questions
Can a narrow book still be valuable?
Yes. A specialized book for a few thousand practitioners can be more useful than a broad book with no clear reader.
Should market size determine whether I write?
Not by itself. Some books are designed for influence, training, legacy or technical reference.
What if I have expertise but no thesis?
Structured interviews and source mapping can surface repeated beliefs, tensions and changes of mind that become the thesis.
