Legislative History research can be a challenging research task. For further assistance, feel free to contact a reference librarian.
Researchers and lawyers use legislative histories in a number of ways --
To conduct legislative history effectively, it is helpful to understand the legislative process, identify the information the process generates, and locate the resources suited to your research goals.
Begin with a compiled legislative history if one exists, or use the following process map, instructional guides, and links to resources to compile one.

The legislative process steps shown in the graphic above are usually associated with materials commonly used in legislative history research.
1) Proposed law introduced in house, senate, or both = bill / resolution
2) Referral to committee / subcommittee for hearing & research = hearing proceedings; committee print
3) Report out of committee to chamber floor = committee report
4) Floor debates = debate proceedings
5) Vote on passage, transfer to other chamber of Congress = conference report
6) Passage, presentation to President for signature = presidential signing statement
Other documents can also be produced along the way. These are considered less as evidence of legislative intent than for other research purposes since they often reflect the work of organizations outside Congress.
1) House and Senate Documents: a catch-all name for documents that House or Senate members consider or produce.
2) CRS Reports: Congressional Research Services, researches and authors reports on legislative topics at Congress's request.
