What is this site?
It is a public reading and navigation service for the current eCFR and imported annual CFR editions.
Is this the official legal edition?
The current eCFR corpus is not the official legal edition. Annual CFR editions are official when available on dated historical views.
How often is it updated?
The current corpus is refreshed from the daily eCFR publication cycle, while annual editions appear as they are imported.
How do I view older text?
Use the version history on a document page or dated routes under /on/YYYY-MM-DD/... to open earlier editions.
