Archives - The GLBT Historical Society Archives had an extremely successful 2024. We received several important grants, digitized new material, and enriched our holdings with newly accessioned collections. We also continued implementation of our digital asset management system, which provides robust digital infrastructure and helps us better preserve and share digitized and born-digital content. We welcomed over 380 onsite researchers working on many different kinds of projects. We continued to expand our online offerings, making 11 new digital archival collections available. In addition, the archives accessioned 66 new collections in 2024.

We presented 3 new exhibitions in the museum space and continued re-building our in-person public programs calendar, hosting 15 in-person public programs and exhibition 4 opening receptions, as well as 1 online workshop. We welcomed nearly 60 schools and community organizations for group tours and nearly 8,000 individual guests visiting the museum. We continue to be specifically guided by the areas of strategic focus as outlined in the society's five-year strategic plan: Women, bisexual people, transgender people, people with disabilities, Black people, Native/Indigenous people, Asian Americans, Latinx people.

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 $850k to $2.5M (+198%).
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 27% · 2018 46% · 2019 47% · 2020 41% · 2021 55% · 2022 50% · 2023 40% · 2024 21%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 8 reported years ran a deficit.

Leadership and staff
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.
Who funds it, year by year
2017 → 2023: the base broadened from 7 funders to 8 funders, grant income rose $75k → $262k.
13 of 31 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 47% 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 Gay Lesbian Bisexual Transgender Historical Society’s funders (the co-funder graph). Top 30 of 31 funders by total. 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
Gay Lesbian Bisexual Transgender Historical Society leans on a few funders — its largest provides 37% of grant income and the top three 66%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
51% 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 Gay Lesbian Bisexual Transgender Historical Society.
Largest funder’s share by year: 2017 27% · 2018 52% · 2019 36% · 2020 40% · 2021 21% · 2022 36% · 2023 39% — growing more concentrated.
“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.
How long its funders stay
36% of Gay Lesbian Bisexual Transgender Historical Society's funders are still giving 3 years after their first grant; 48% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
Gay Lesbian Bisexual Transgender Historical Society draws 75% of its grant income from funders outside California, across 9 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.2M arriving through sponsors registered in 9 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.
