From Eric Klinenberg’s Palaces for the People pg 33-34:
Libraries are not the kinds of institutions that most social scientists, policy makers, and community leaders usually bring up when they discuss social capital and how to build it. Since Tocqueville, most leading thinkers about social and civic life have extolled the value of voluntary associations like bowling leagues and gardening clubs without looking closely at the physical and material conditions that make people more or less likely to associate. But social infrastructure provides the setting and context for social participation, and the library is among the most critical forms of social infrastructure that we have. 5
From pg 38, my emphasis:
Why have so many public officials and civic leaders failed to recognize the value of libraries and their role in our social infrastructure? Perhaps it’s because the founding principle behind the library—that all people deserve free, open access to our shared culture and heritage, which they can use to any end they see fit—is out of sync with the market logic that dominates our time. (If, today, the library didn’t already exist, it’s hard to imagine our society’s leaders inventing it.) But perhaps it’s because so few influential people understand the role that libraries already play in modern communities, or the many roles they could play if they had more support.
