Families preserve old diaries against the losses of Alzheimer's in two parallel ways: protecting the physical books with archival storage and digitization, and capturing the context around them — who wrote what, when, and why — while the writer can still tell the story. The urgency is real: the Alzheimer's Association reports that 7.2 million Americans age 65 and older are living with Alzheimer's dementia in 2025, supported by nearly 12 million family caregivers.
A diary is often the last first-person record of a life. Once the writer can no longer explain a nickname, an abbreviation, or a gap of missing years, that meaning is gone even if the paper survives. Preservation therefore means both conserving the object and recording its story.

Where and how to store the original diary
Paper is destroyed slowly by heat, humidity, acid, and light. The National Archives advises families to store papers below 75°F and below 65% relative humidity — but above 15% humidity, since overly dry air makes pages brittle — in lignin-free, acid-free boxes or folders. That usually means a closet on a main living floor, not a basement, garage, or attic.
Keep diaries away from damp walls, plumbing, and heat sources. If a diary has loose pages or a crumbling binding, place it flat in an acid-free box rather than forcing it upright on a shelf. Resist the urge to display it. The Library of Congress warns that permanent display of paper items is never recommended because light damage is irreversible; frame a copy and keep the original stored.
How to digitize it well
A scan protects against fire, flood, and simple loss, and lets far-flung relatives read the same pages. NARA's digitization standard for permanent records is at least 300 dpi saved as uncompressed TIFF, and preservation advisors suggest 600–1200 dpi when families may want larger reproductions of handwriting later.
Practical steps: A scan alone is not enough. Photo-organizing professionals note that digitized diaries need attached stories and metadata — labels, audio recordings, and context — because an unlabeled image loses meaning for future generations.
- Scan or photograph every page, including covers, blank pages, and anything tucked inside.
- Save master files as TIFF; make JPEG or PDF copies for everyday reading.
- Name files by date and volume (for example, `1962-diary-vol2-p014`).
- Keep at least two backups in different places, such as an external drive and cloud storage.
Capture the story while it can still be told
This is the step families most often postpone, and the one Alzheimer's forecloses first. Sit with the diary's author, or the relative who knows it best, and record them reading favorite passages and explaining people and events. StoryCorps has done this at scale: its Memory Loss Initiative, launched in 2006, has recorded more than 2,000 family interviews with people experiencing memory loss, now archived at the Library of Congress.
Work in short sessions, ideally at the person's best time of day. Ask open questions — "Who is this?" "What was happening that spring?" — and let the diary itself prompt recall. Handwriting and paper texture carry sensory cues a screen does not, which can help trigger recognition. Write down or record the answers immediately, keyed to page numbers, so the annotations stay attached to the scans.
Turning diaries into memory books — what the evidence supports
Many families excerpt diaries into a life story or memory book for the person with dementia. Dementia-care guidance recommends pairing each photo or diary excerpt with a short first-person caption naming the person, place, and event, and involving the person in choosing the contents. The evidence for benefits is real but modest.
A 2024 systematic review found life story books are associated with improved well-being and quality of life in people with dementia, though evidence for effects on depression, cognition, and agitation remains inconclusive. An Australian summary of 11 systematic reviews reached a similar verdict on reminiscence therapy: possible quality-of-life gains, no identified harms, but no established cognitive benefit. So frame the project honestly: preservation is about legacy, identity, and connection — not slowing the disease.
If disaster strikes the diary
Water and mold are the emergencies most likely to destroy a diary outright, and the response window is short. The Library of Congress advises that wet papers be spread out to air dry immediately — or frozen if they cannot dry within two days, since freezing halts mold growth until you can dry pages properly.
For items already stained by mold, keep them isolated from other papers and stored at 40–65% relative humidity to prevent regrowth. Handle moldy pages outdoors or in a ventilated space, and consider a conservator for a badly damaged volume — one reason the digitized copy should already exist before any emergency.
Frequently Asked Questions
Should we laminate fragile diary pages?
No. Lamination is irreversible and damaging. Use acid-free folders and boxes instead, per National Archives family-archive guidance, and handle originals as little as possible once scanned.
Is it better to give the person with dementia the original diary or a copy?
Use the original for supervised reminiscence sessions — its handwriting and texture can aid recognition — but keep it stored safely otherwise and use printed copies or a memory book for everyday handling.
What resolution is enough if we only plan to read the scans?
300 dpi meets NARA's standard for permanent records, but 600 dpi or higher is wise if anyone may later want enlarged reproductions of the handwriting.
