"Legislative histories cite congressional publications and daily Congressional Record debate associated with each public law. Referenced publications may include congressional reports, hearings, documents, and/or prints. A legislative history compilation enables researchers to trace the development of a law from its earliest consideration to its signing by the President." (LN Congressional)
