FederalRegister.gov is a prototype, unofficial web portal that presents XML renditions of daily Federal Register documents and links to the official PDFs on govinfo.gov. Operated as an OFR/GPO partnership, it aggregates notices, proposed rules, rules, and presidential documents from U.S. agencies and provides search and browse tools for current and past issues. Although it aims to become the ACFR-sanctioned XML-based Federal Register, it is not the official legal edition and users should verify results against the official edition on govinfo.gov for legal purposes.
