Walk into a small museum, a parish archive, or the back room of a town library almost anywhere in the world, and you’ll find the past in boxes. Photographs, letters, ledgers, maps, recordings. Someone kept them. Someone cared enough to keep them dry. Much of this material has never been described, and much of the rest only barely.
Kept is not the same as found
A collection moves through stages. It is preserved. It may be digitized. It may be described: given names, context, relationships, and an account of what remains uncertain. Only then is it discoverable, by people and by machines.
Most collections stall somewhere along the way, and not because anyone failed. Archivists learned long ago to describe collections as wholes rather than item by item, so that more of them could be opened at all. In 2005, the archivists Mark A. Greene and Dennis Meissner called this approach “More Product, Less Process.” A finding aid that says “Photographs, 1950–1990, three boxes” makes a collection usable. That finding aid doesn’t make the thousands of photographs inside the boxes findable. The photographs are both described and underdescribed.
Digitization isn’t the answer on its own
It’s tempting to think that putting everything online solves the problem. It doesn’t. A scanned photograph with a file name and nothing else is still dark. Once the photograph is on the open web, it may also be gathered up to train AI models, without permission and without anyone describing it. The photograph enters the great compendium of machine-readable knowledge, but not as itself. It is absorbed, not found.
Description is scarce
The historical record is abundant. The labor to describe it is not. Most of the world’s history organizations are small. Many run on little money. They don’t lack collections or care. They lack time.
UNESCO estimated that about 104,000 museums operated worldwide in 2020. Reliable global figures on their size are scarce; the United States keeps the most detailed count.
In the United States alone, 21,588 history organizations operate. More than 60 percent of the private nonprofit ones report annual revenue under $50,000. More than 80 percent report under $200,000.

Search has changed, and it hasn’t
For generations, finding the past meant printed catalogs and browsing shelves. In the digital age, finding the past meant search engines, and the advanced search box on an archive’s website. Even then, much of the record was hard to discover. Material that hadn’t been digitized, or whose finding aid said little, stayed hidden. People asked questions and got lists and hints. Then they went to look, often in person, often with an archivist’s help.
That difficulty hasn’t changed. What AI changes is what comes back when you ask. Instead of a list of leads that invites you to keep looking, you get a finished answer that seems complete. The answer can draw only on what has been described somewhere. The risk isn’t that AI will invent the past. It’s that AI will keep finding the same past, and make it harder to notice what’s missing. Nothing is being destroyed. Much is being left out.
Why this is exciting
Archives and libraries have changed their tools before. In 1966, the Library of Congress began sending out catalog records that computers could read, in a format called MARC, developed under Henriette Avram. Over the decades that followed, MARC let libraries share their catalogs and changed how the world found books. But MARC taught machines to read descriptions. People still had to write them.
What’s new is that machines can now read the objects themselves: a photograph, a handwritten ledger, a faded sign. Machines can do that reading consistently and at scale, which is exactly the work there has never been time for. The same technology that threatens to leave this material out may also help bring it in.
Reading is not yet describing, though. A good description carries what a collection’s keepers know: who is in the picture, why it matters, what should stay private. The opportunity is to put the machines’ capacity in the service of the curators’ knowledge, not in its place.
AI can’t give curators more time. But it can do something else. AI can help them to describe at a scale not previously imagined, which answers the shortage of time another way.
The harder question is whether curators can describe at that scale on their own terms. That question is the heart of ARCADE. We think the practice we’re developing helps them do just that.
