The following are two links that answers that question. The first link is to the website of the General Court (the State House for all intents and purpose). On this home page you will find nearly everything one needs: RSAs (the Laws of NH), House Rep info, Senate info, links to streaming media, etc.
The second link brings you directly to the “House Calendar” page. The House Calendar is published each week and contains general information as well as notices of bills, study committees, public hearing dates for legislation, etc.
For those interested in knowing just what is occurring in Concord, these links are great!
