Comparison method

How to read the changes

America.co links each public law to its bill using GovInfo law metadata and official Bill Status records. We compare the earliest dated GovInfo bill text in that record with its enrolled text, the version sent to the President. Earlier versions can be introduced, reported or passed text depending on what GovInfo supplies.

We compare provisions inside the legislative body and omit the table of contents. Quoted statutory language stays with the provision that quotes it.
We pair provisions with exact wording, the same number and heading, a unique heading, a single provision in both documents, or strong shared wording. The pairing method is displayed alongside each result.
Text excerpts highlight up to three changed passages per paired provision. Use the full versions for context, definitions, and the rest of the amendments. Unmatched provisions are listed separately because changes in structure or wording can prevent reliable pairing.
The public law is linked separately. For the current statutory text, consult the United States Code and subsequent amendments.
