From an image to a readable record
An image of a letter preserves how it looks. It does not let you search it, compare it with other documents or follow the people and places it mentions. The first step is to turn every image into a structured record, while keeping each piece of text anchored to where it sits on the page.
What the outlines show
Every outlined area is one part of the page: an address, a postmark, a stamp, a censor’s mark, a paragraph of a letter, a signature. For each part the record holds what kind of part it is, how it was made — handwritten, typed, printed or stamped — where it is on the page, and the words it contains. The colours group the parts by how they were made.
Honest about what cannot be read
Old documents are faded, stained, creased and overstamped. Where a word or a whole part cannot be read with confidence, the record says so rather than guessing, and it is shown here as unclear. Some documents have been checked and corrected by a person. Others show the automated reading exactly as it was produced, with nothing tidied up afterwards. Each document tells you which it is.
Why it matters
Once every part of every page is recorded like this, a collection can be searched by name, place or date. Postmarks can be lined up into journeys, and people can be traced from one document to the next. Individual pieces of evidence can be cited precisely. The stories on this site are built on exactly this kind of record.
