About Sources of Compiled Legislative Histories
Legislative histories are collections of documents produced by Congress during the enactment of a law, serving as the “working papers” behind the statutory language. Legal professionals and researchers rely on these materials to uncover legislative intent and resolve ambiguities.
This resource was originally created by the late law librarian Nancy P. Johnson and is now updated by professional law librarians Austin Williams and Jenna Fegreus. The latest edition organizes its content into two types of legislative histories: commercial sources and topical arrangements, as well as a comprehensive collection of histories for major laws. It also includes an Author-Title Index and a Public Law Index for streamlined navigation.
The fully searchable database makes it easier than ever to access this information, with online content continuously updated to reflect new legislative histories.
