About these numbers
From the Public Libraries Survey, fiscal year 2024.
- Hours are an average. The survey reports a building’s public hours for the whole year. We divide by the weeks it was open, so check the library’s own site for today’s hours.
- Compared by size. “Similar-size” means libraries serving about as many people, nationwide. Per-resident numbers always flatter the smallest towns, so they’re never compared with big cities.
- The library’s own count. Libraries report their own visits, loans and programs. A library that didn’t respond keeps its address and hours here, with no numbers.
- System-wide. Twin Rivers Branch Library is one branch of Mercer County Library, so the yearly numbers cover every branch and all 168,771 people it serves.
