Legislative History - Federal and State

Introduction to State Legislative History Research

The process for conducting state legislative history research is much the same as it is for conducting federal legislative history research with the caveat that state materials may not be as available depending on what law-making procedural records the legislature keeps and whether state resources have been dedicated to preserving and making them available.  

To begin research into state statutes and legislative history, it is best to consult a research guide to learn something about legislative procedures in the state and what resources are available.  

State law libraries, legislative research libraries, or university law libraries often provide the best access to legislative materials and have knowledgeable librarians to assist with research questions.  In addition, researchers can usually request scans or copies of print materials that have yet to be made available in digital format. 

Guides to State Legislative Resources at Biddle Law Library

Below are books, bibliographies, and guides available through Biddle's catalog that provide state law research guidance.  Compiled or subject-specific state legislative histories can be found by searching the Biddle Law Library catalog using the subject matter of the legislation (e.g., "water law" and the name of the state).  In addition, bar journals, available through the Lexis, Westlaw, or Bloomberg, often contain articles about state legislation.
