In March of 2010, the New Hampshire Political Library merged with the New Hampshire Institute of Politics to join forces behind shared missions. The Institute upholds the Library’s role in increasing civic engagement in the democratic process by promoting and preserving the state's unique political traditions and passing them on to future generations. Many of these traditions include opportunities for voters and community leaders to meet presidential candidates ahead of New Hampshire's first-in-the-nation primary.

Several of the Library's programs and forums are now offered by the Institute, including the New Hampshire Primary Awards, Politics & Eggs, Candidate Café, Conversation with the Candidate, and Voter Registration. 

The Institute also works closely with the New Hampshire State Library and Archives to maintain a collection of political memorabilia, papers, and photographs spanning over half a century. Various items from the collection are on display throughout the year at the New Hampshire Institute of Politics and accessible weekdays from 8:30 a.m. to 4:30 p.m.
