The average home runs an information system nobody designed on purpose: a junk drawer functioning as an unindexed archive, a pile of mail acting as an inbox with no triage rule, a shoebox of old photos serving as cold storage nobody has migrated in a decade. None of it was planned. All of it is, functionally, an information architecture — just one that emerged instead of being designed.
Emergent systems still have rules
Watch how a household actually uses a junk drawer and you'll usually find informal rules operating anyway: recently used items migrate to the front, truly forgotten ones sink to the bottom, occasional purges happen under specific pressure, like moving house or running out of room. It's a working system, just one running entirely on tacit knowledge instead of documented policy — which is exactly why only the people who built it can actually use it, and why a new housemate finds the drawer completely opaque.
What professional archives get that homes don't
The gap between a junk drawer and an archive isn't materials or technology. It's documentation: an archive writes down its own logic so someone who didn't build the system can still use it. A home rarely does, which is why sorting a deceased relative's papers is so often described as archaeology rather than filing — the system was real, it simply never wrote itself down for an outsider to read.
Every home is already running an information architecture. The only question is whether anyone besides its author can use it.
The cheapest fix most domestic archives need isn't more storage. It's a two-line label explaining a system that already, mostly, works.
