Program
Andrew carnegie once envisioned public libraries as places of learning and equal opportunity. Since 1895, Carnegie Library of Pittsburgh (clp) has been present for every challenge and opportunity facing our community while also engaging people in literacy and learning. While books and materials remain the heart of the library, clp has transformed into a community cornerstone that focuses on education, workforce and economic development, and neighborhood vitality. The library empowers people of the pittsburgh region and helps transform their lives through lifelong learning, digital literacy, and connections to others. At the library, ideas, people, and community partners interact to create positive change. (continued on schedule o)

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. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2019 to 2020, from $105M to $120M (+14%).
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 71% · 2018 63% · 2019 71% · 2020 71% · 2021 74% · 2022 79% · 2023 67% · 2024 82% · 2025 81%. Grants only. Government contracts and fees sit inside program revenue.

Who funds it, year by year
2017 → 2023: the base broadened from 25 funders to 45 funders, grant income rose $636k → $1.4M.
11 of 103 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 9% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
Left out of every figure on this page: $15M from 6 payers (the payer shares this organization's board, largest Jack G Buncher Charitable Fund for the Carnegie Library of Pittsburgh). These are real filings, and they are not money CARNEGIE LIBRARY OF PITTSBURGH raised.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $748k 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.
