About
Provenance, and how this book was built
This book was built like a research project, and the audit trail is part of the book. Every fact, date, name, quotation, and image traces back to a source that a person read in full, and every disagreement between sources is logged rather than smoothed over.
The research ran as ten domains writing into one shared register, was revised four times in August 2026, and folded in fourteen sources obtained through the Boston Public Library. Where a source could not be obtained, the book says so in plain sight and rests no claim on it.

| Disagreements between sources, logged | 129 |
| Of those, resolved from the sources | 58 |
| Primary-source images rights-cleared | 43 |
