How to preserve old family letters and documents

Letters survive house clearances in a way almost nothing else does — tucked into a book, bundled with string in a drawer, kept because nobody could quite bring themselves to throw them out. What usually doesn't survive is the context: who "Dear Vi" was, why the 1962 letter mentions a house that no longer has a number, whether the argument in the fourth paragraph was ever resolved. The paper keeps itself, more or less. The story behind it needs someone to ask while there's still someone who knows.

Storing the letters themselves

This part is mechanical, and a University of Nottingham conservation guide for people with family papers at home sets it out plainly enough to follow without any special equipment.

• Keep them out of attics, cellars, garages and sheds. The guide is specific about why: those are the parts of a house most exposed to "extremes of temperature, damp, dust or flooding" — a spare room or a cupboard in a normally-heated part of the house is a better home for them.
• Store flat, in acid-free folders or boxes, somewhere cool and stable. Not bent into a shoebox at an angle for years, and not somewhere the temperature swings with the weather.
• Take out paperclips, metal staples and elastic bands. All three deteriorate over time and leave stains or damage on the paper they're attached to.
• Never glue or tape a loose letter into a blank album or scrapbook. The glue damages the paper, and a full album puts pressure on its own spine — keep letters loose in a folder instead.
• If anything gets damp, don't dry it near heat. Carefully separate the sheets, lay them flat on blotting paper and let them dry in the air — not over a radiator or in front of direct heat.
• Handle them with clean, dry hands, and make notes in pencil rather than pen if you're working near the originals — skin oils, dust, and ink all mark paper that's often decades old already.

Digitising them

A phone camera, good light and a flat surface will give you a readable copy of most letters; a flatbed scanner will give you a better one. Lay the letter flat, shoot from directly above rather than at an angle, and photograph both sides if anything's written on the back. Do this before you do anything else to an original: once there's a photograph, the worst case stops being "it's lost" and becomes "it's been copied and I still need to look after the real one".

The part the paper can't tell you

A letter answers what was written. It doesn't answer who the people in it were to each other, what else was happening that year, or what became of whatever it describes. That context lives in whoever's still around to supply it — and it's worth asking for deliberately, rather than hoping it comes up.

1. 1

   Go through them together, not alone

   Reading old letters with the person who kept them turns a filing task into a conversation. A line that means nothing to you — a name, a place, a joke — often means a great deal to them, and you won't know which lines those are until you ask.

2. 2

   Ask who everyone is while someone can still say

   Write the answer on a separate sheet kept with the letter, or in pencil on its envelope — not directly on the letter itself. Names that feel obvious to keep in your head now are exactly the ones that get forgotten in ten years.

3. 3

   Ask what happened next

   A letter is a single moment. "Did that job work out?", "Did they ever make it over?", "What happened with the thing in the last paragraph?" are the questions that turn one letter into an actual story rather than an artefact.

A box of old letters is a genuinely good way to start a conversation with a parent or grandparent — bring one, ask what it was about, and let the questions follow from there rather than starting from a blank page. If you want something to carry that on week by week, StoryPrompt emails one question at a time from a fixed set of 52 about a British life, they type their answers, and every answer collects into a book. It doesn't hold scans of the letters themselves, so keep those alongside it.
