The best thing you can do is ask your librarian. Libraries are often poorly funded, very much so in rural areas. They are often partially funded with donations.

Somebody was willing to step up and rehab a local library. Had they not done so, it would have been forced to close. It is staffed entirely by volunteers. The town can barely afford to budget the heat.

Fortunately, the same person now donates regularly and there's no risk of immediate closure. They will have also left a small trust for the library when they pass away.
