What North Haven Historical Society does
Mission
The North Haven Historical Society works to discover, collect, preserve, and share the rich, layered history of North Haven and its surrounding areas.
As stated on its FY2025 Form 990.
Programs
North Haven Historical Society (NHHS) maintains the North Island Museum, containing a replica of a turn-of-the-century parlor, kitchen and bed chamber with an open gallery. In two outbuildings, there are displays of farm implements and small boats. In addition, NHHS houses its collection of archival materials in a separate climate-controlled archives building. The collection consists of town ledgers, town meeting records, old deeds and letters, and historical photographs, slides and scrapbooks donated to the museum.

The organization over time
Each line starts at 100 in 2019, so what you read is the shape rather than the size: 150 means half as much again as 2019, 50 means half. The number beside each label in the key is where it ended.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2021 to 2022, from $1.4M to $1.3M (−6%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2019 5% · 2020 10% · 2021 22%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 6 of the last 7 reported years ran a deficit.

The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.
