The organization over time
Each line starts at 100 in 2020, so what you read is the shape rather than the size: 150 means half as much again as 2020, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
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: 2020 18% · 2021 18% · 2022 2060% · 2023 16% · 2024 19%. Grants only. Government contracts and fees sit inside program revenue.
64% of ERWIN LIBRARY AND INSTITUTE’s revenue is contributions — more donation-reliant than the typical peer (58% for the typical peer).

Who funds it, year by year
2018 → 2023: the base broadened from 1 funder to 4 funders, grant income rose $700 → $17k.
3 of 6 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 60% 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 ERWIN LIBRARY AND INSTITUTE’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
ERWIN LIBRARY AND INSTITUTE leans on a few funders — its largest provides 51% of grant income and the top three 90%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
61% 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 ERWIN LIBRARY AND INSTITUTE.
Largest funder’s share by year: 2018 100% · 2019 100% · 2020 55% · 2021 55% · 2022 44% · 2023 44% — diversifying over time.
“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
60% of ERWIN LIBRARY AND INSTITUTE'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 $35k that is directly attributable, 98% of it comes from New York funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $53k 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.
