What History of Science Society Inc does
Mission
The society's mission is to foster interest in the history of science, promote discussion of science's social and cultural relations, and bring this understanding to others worldwide.
As stated on its FY2025 Form 990.
Programs
Publications - the society publishes two journals: isis appears quarterly and osiris appears annually. Using a highly selective process, the society ensures that each journal carries the best scholarship in the history of science. The editorial boards help the editors review the manuscripts under the overall direction of a committee on publications. Isis and osiris are sent to some 3,000 subscribers. The hss also publishes the annual isis current bibliography (cb) as a supplement to isis. Each cb contains thousands of entries, which are also loaded into the history of science, technology and medicine (hstm) database, published by ebsco, and freely available to individual members. Nonmembers can access much of the bibliographic data at no charge at www.isiscb.org.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 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 $4.9M to $4.0M (−18%).
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: 2017 13% · 2018 10% · 2019 11% · 2020 18% · 2022 2%. 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 9 reported years ran a deficit.

2 of 3 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 94% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of HISTORY OF SCIENCE SOCIETY INC’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
HISTORY OF SCIENCE SOCIETY INC leans on a few funders — its largest provides 94% of grant income and the top three 100%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
94% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund HISTORY OF SCIENCE SOCIETY INC.
Largest funder’s share by year: 2018 100% · 2019 100% · 2020 100% · 2021 100% — broadly stable.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Where its funders are
94% of HISTORY OF SCIENCE SOCIETY INC's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $5k that is directly attributable, 100% of it comes from funders outside Pennsylvania, across 1 state.
Funder states come from each funder’s own filing. $78k arriving through sponsors registered in 2 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
