Using the health care legislation passed in 2010 as a model to show how legislative procedure shapes legislative history, this article posits that legislative procedure has changed, making the traditional model of the legislative process used by law librarians and other researchers insufficient to capture the history of modern legislation. To prove this point, it follows the process through which the health care legislation was created and describes the information resources generated. The article concludes by listing resources that will give law librarians and other researchers a grounding in modern legislative procedure and help them navigate the difficulties presented by modern lawmaking.
