Look for an Article
In many instances, a law review article may discuss the legislative history of your statute, saving you the trouble of examining each individual document. Thus, one helpful strategy is to begin by Keyciting (Westlaw Edge) or Shepardizing (Lexis+) your statute and then looking at citing law reviews. Once you're in the Citing References, narrow to secondary sources then run a "Search Within" to search only the secondary sources (i.e. law reviews) that have cited to your statute. A good search syntax in Westlaw: ATLEAST5("legislative history") Running that search within the filtered citing references will retrieve secondary sources that have at least five instances of the phrase "legislative history" in the article. You could broaden this search to opinions; occasionally you get lucky and find a court opinion discussing the legislative history of a statute. Taking the time to search for an article or court opinion with this kind of discussion is a worthwhile first research step.
