Legislative History Research Guide : Legislative Research in Other States

The legislative history of a law is comprised of the documents created during deliberations leading to the law's enactment. They are used to determine the legislature's intended purpose and to clarify any ambiguities in the language. - Gail Whittemore -

Legislative Histories in the States

State legislative history can be difficult to find: each state preserves different types of materials (sometimes no material at all) as legislative history; coverage can be spotty, both in terms of dates covered and also the kinds of legislative history documents available for different laws, even in the same jurisdiction; not everything is available online; and there may not be any compiled histories for state statutes.
