Archival Science

No One Indexes the Index

Every archive has a finding aid. But who documents the documenters?

I spent the better part of March 2024 inside a cold room on the third floor of the records annex, hunched over a reader-printer last serviced in the early 1990s. The fiche I was pulling—county tax assessments from 1883—had been converted to film in 1974 and never touched again. The frames scrolled past in negative: pale script on a dark field, every s looking like an f, every column sum a small act of faith. I was the first person to read these records in fifty years. But I was not the first person to index them.

The Finding Aid Problem

Catalogers build finding aids to surface records. Archivists arrange fonds and series. But the finding aid itself—the index, the controlled vocabulary, the cross-reference schema—is a record too, and it decays in ways the primary documents do not. A tax roll from 1883 outlasts the card catalog that points to it. We treat indexes as infrastructure when they are, in fact, artifacts. Fragile ones.

An index is a promise that a record exists. When the index breaks, the record might as well not.
