New York State Legislative History

The Legislative History of a New York State Law: A Tutorial and Guide to Library Sources: The New York State Library has authored this 12 step guide to conducting legislative history research in New York. It is a must read before beginning any legislative history research in New York State.

Bill Jackets: For information beyond prior statutes you can look to the bill jackets. NY State has digitized bill jackets for laws passed after 1995 on the New York State Archive Website. Additionally, some laws prior to 1995 have been digitized and are available at the New York State Library’s Digital Collections website. However not all laws have been digitized and some may be unavailable.

If what you are looking for is not on either of the above you have two options.

  • New York Legislative Service: This is a for profit company that has access to bill jackets for New York state laws. For a fee, they will scan and email you copies of the law you are looking for. If you are doing this research for your law firm, this may be something they are willing to pay for.
  • New York State Library  or University of Buffalo Library. These two libraries may also have physical copies they can scan to you. This may take longer than the New York Legislative Service. There may also be a small photocopying fee.
