GovInfo vs HeinOnline

GovInfo is a free web and API service providing public access to official publications from all three branches of the U.S. Federal Government. Users can browse by alphabet, category, date, committee, or author, and search publication metadata. The API exposes content and metadata in self-describing packages, while selected collections offer machine-readable bulk files such as XML with schemas, stylesheets, and guides. Searches cover case law, statutes and regulations, and legal commentary, including opinions from more than 100 U.S. courts. PDF files receive digital signatures and a visible authenticity seal that can be checked in Adobe Acrobat or Reader. The preservation repository keeps at least two geographically separate archival copies, weekly backups, a standby recovery instance, virus scanning, and fixity checks; GPO reports ISO 16363:2012 certification from December 28, 2018. The responsive site works on mobile without a separate app or URL. A public-preview MCP server supports integrations with large-language-model workflows. Full text is limited to publications stored on GovInfo.
