A Billion Wi-Fi Sessions: Libraries As Digital Infrastructure

Second in Library Overview: Community Usage & Access

Looking at a decade of IMLS Public Libraries Survey data on how Americans actually use public libraries, one number frames the entire conversation: Wi-Fi sessions grew from 125 million in FY2014 to 515 million in FY2023. That’s a 312% increase. At the same time in-person visits decreased, physical circulation plateaued and then COVID crushed it. And Wi-Fi usage grew every single year. That tells you something about the changing definition of what the library has become — not a building you go to, but a bandwidth node you connect through. The library is no longer constrained by the limits of its physical location it has become a key component of our digital infrastructure. It is this current operational reality that the sector’s funding arguments have not yet fully caught up with.

The Visit Story Is More Complicated Than the Headlines Suggest

In-person visits peaked at 1.55 billion in FY2014 and were already in structural decline before COVID arrived. By FY2019, visits had fallen to 1.39 billion — a drop of roughly 160 million visits over five years that happened with no pandemic, no widespread closures, and no dramatic service reductions. Something structural was shifting long before March 2020. Then COVID hit: visits crashed to 492 million in FY2020, a decline of 64.7% in a single year. Recovery has been real — 1.31 billion visits in FY2023, approximately 94% of the FY2019 baseline — but the sector has not returned to its FY2014 peak, and given the pre-COVID trajectory, there is no reason to expect it will.

Understanding that pre-COVID structural shift matters for how libraries think about their service model. Declines are not evidence of a failure of program quality or staff performance, rather is reflects larger behavioral shifts exhibited across retail, banking, government services, and entertainment: Americans were increasingly meeting their needs digitally. Just as fewer customers visit a bank, the library’s physical footprint was serving a narrower (though no less important) share of their total information and service needs. Despite this shift, data confirms that libraries remain relevant, but how they execute on this relevancy has fundamentally changed.

Card Penetration, Circulation, and the Strategic Question Nobody Is Asking

Library card penetration was essentially flat throughout the entire decade — 56–57% of the U.S. population with active or registered cards, yielding 185.2 million registered borrowers in FY2023. That flatness is notable in the context of the entire US populations which grew by approximately 15 million. New cardholders are being added, but at a slower rate than population growth. That raises a question the sector needs to address: If digital circulation is surging while card registration is flat, libraries may be deepening engagement with existing cardholders and not reaching new patrons. That’s not necessarily a failure, but it’s a strategic choice with stakeholder implications — particularly if the unregistered 43% skews toward communities with the least access to alternative digital resources.

Physical circulation tells a familiar story: public library physical circulation fell from 2,402 million in FY2014 to a COVID low of 1,248 million in FY2020, then recovered to 2,188 million in FY2023 — a substantial (but partial) recovery. Academic library physical circulation is a different and starker picture: structural long-term decline of approximately 49% over the decade, with only partial and unconvincing post-COVID recovery. Academic physical circulation was already in freefall and there are have been many articles written about academic libraries reclaiming floor space for student usage as digital content expands on campus. COVID merely exacerbated the trend.

Digital circulation, by contrast, grew every single year, including FY2020. Public library digital circulation went from 128 million in FY2014 to 652 million in FY2023, a gain of 410%. Academic digital circulation grew 259% over the same period. A meaningful part of the supply-side explanation for this is simple: Publishers pushed more digital content which libraries subscribed to, and patrons accessed. E-book titles accessible to public library patrons exploded from 3.2 million in FY2014 to 32.5 million in FY2023 — an increase of 916%. Physical volumes held, meanwhile, fell from 798 million to 680 million, a decline of 14.8%. The collection is shifting. Usage is following the collection.

From Computer Labs to Bandwidth Nodes: The Infrastructure Transition

The computer session vs. Wi-Fi crossover is one of the clearest signals of the library’s infrastructural transition. Public access computer sessions declined from 338 million to 278 million over the decade. Wi-Fi sessions surged from 125 million to 515 million. The crossover happened around FY2018 — the point at which patrons bringing their own devices and using library bandwidth surpassed the number of patrons using library-owned terminals. This has profound implications for how libraries think about infrastructure investment: the case for buying and maintaining large fleets of public computers weakens as the case for robust, high-capacity wireless infrastructure strengthens.

Hotspot lending data makes the investment case even more concrete. The number of libraries offering hotspot lending programs grew from approximately 250 in FY2014 to 6,850 in FY2023 — a 27-fold increase. Units in active circulation grew from 18,000 to 682,000, an increase of 3,689%. COVID and CARES Act funding dramatically accelerated this in FY2020, providing emergency capital that many library systems used to build out hotspot nodes at scale. Pew Research data indicates that approximately 26–27% of U.S. adults used library internet access in the twelve months preceding the FY2022–23 survey, with rural and low-income adults disproportionately represented.

Reference services are completing a parallel transition. In-person reference transactions fell from 285 million to 205 million over the decade. Virtual reference — chat, email, SMS — grew from 28 million to 122 million. Virtual reference now accounts for 37% of all reference transactions, up from 9% in FY2014. The reference desk is not dying. It’s moving online, serving a different workflow at a different pace, often with higher complexity questions as patrons handle routine research themselves.

The library’s role as physical community anchor has recovered since COVID but it is fundamentally changed. Public libraries are now front and center in the effort to equalize access to digital infrastructure and online content and their influence is growing. Over the next few years it is unclear whether funding resources will advance this trend further. The systems that subsidized hotspot access and lending (CARES Act, Emergency Connectivity Fund, Digital Equity grants) are being reduced or eliminated. The trend will not reverse itself and if anything it is intensifying. The gap between what the digital equity infrastructure requires and what current funding structures provide is widening. This is a problem worth watching closely, and a gap worth naming explicitly in every advocacy conversation the sector has with Congress and state legislatures.
