I actually agree with the article, but this piece feels like a conflict of interest — a library conducting research on how libraries improve everything.
Anecdote: While chronically underfunded to a overwhelming degree, local libraries and their staff in my area have consistently stepped up to the plate by trying to support the communities. Most notably when schools around here stopped offering any sort of afterschool/enrichment programing internally for kids, the libraries basically just added to their model.
Doesn't that provide sufficient foundation for a more even evaluation?
