The Index That Outlives the Reporter

Every long inquiry eventually reaches a point where the reporter who built the file is no longer the only person who needs to understand it — an editor asks for the source of a specific claim, a colleague picks up the story during leave, or a legal read requires someone unfamiliar with the material to locate exactly what supports what. If the evidence store only makes sense to the person who assembled it, that moment becomes a crisis rather than a routine handover.

The fix isn't complicated, but it does require deciding on a structure early and holding to it, rather than improvising folder names as documents arrive. A workable evidence room starts with a simple, consistent naming convention — date, source, and a short description, in that order, applied to every item without exception — so that a folder listing alone tells a reader roughly what they're looking at before they open anything.

An index is a map, not a filing cabinet

Alongside the files themselves, a running index — a single spreadsheet or document listing every item, where it came from, when it was obtained, and which specific claim in the draft it supports — turns a folder of documents into something a colleague can actually navigate. The index doesn't need to be elaborate. It needs to be complete, current, and written so that someone with no prior context can trace a sentence in the story back to the record behind it.

Keeping originals separate from working copies matters here too. Once a document has been annotated, highlighted, or excerpted for drafting, the unmarked original should still exist, untouched, in its own place. This protects against a working copy's annotations being mistaken for the source material itself, and it means a later, more careful read is always possible.

A review pass finds the single-source claims

Perhaps the most useful habit is a periodic review pass through the draft against the index, checking which assertions currently rest on only one document or one source. This isn't about distrust of the material — it's about knowing, honestly, where the file is thin, so that a second source can be sought before publication rather than after a challenge.

Backups, kept somewhere separate from the working machine, round out the practice. None of this is glamorous work. But an evidence room built this way survives the departure of the person who built it, and that durability is, in the end, what makes a substantial inquiry safe to finish.
