Richardson School of Law Library all have many legislative histories in print and microfiche. Search for them using OneSearch.
Refer to the Published legislative histories tab for more sources. If you can't find a compiled legislative history for a law, you can do your own research to find documents associated with its passage. Ask a librarian for assistance with finding legislative histories.
