You can search legislative histories from the Basic, Advanced, and Search by Number Forms.

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. Legislative histories from 1984 forward contain numerous hypertext links to abstracts for congressional publications, and legislative histories from 1995 forward contain hypertext links to the daily Congressional Record.
