About eCFR.io

About eCFR.io, its source material, and how current and annual editions are presented.

eCFR.io is a fast public reading interface for the Electronic Code of Federal Regulations.

Current pages follow the daily eCFR editorial compilation. Historical annual views are based on imported annual Code of Federal Regulations editions.

The site preserves familiar public CFR paths while separating current material from dated historical editions.
