Keep sources distinct
Audio and photographs are original materials; transcripts, event summaries and chapters are derived. Preserve a route back to the source.
Check people and time
Build a person index and timeline. Use approximate dates or attributed memories where proof is limited.
Do not invent context
Historical background can explain conditions, not supply experiences no one recalled.
Choose privacy item by item
Storage, family sharing and public display of illness, conflict or private photographs are different decisions.
Record family review
Have the appropriate people confirm facts, tone and sharing scope; recheck chapters affected by later corrections.
