How a hospital librarian spends their days

In an era where artificial intelligence promises to democratize information, Anne Helen Petersen reveals a darker reality: the very tools meant to accelerate discovery are actively degrading the quality of medical evidence. This piece is not a nostalgic look at dusty stacks, but a urgent dispatch from the front lines of healthcare, where librarians are now the primary firewall against algorithmic hallucinations and state-sponsored disinformation.

The Human Firewall Against Algorithmic Noise

Petersen introduces us to Carrie Grinstead, a hospital librarian whose daily reality contradicts the popular assumption that "everything is on the internet." Grinstead describes a profession that has shifted from curation to crisis management. "These days I also fight with all the AI bots that generate fake citations, spit out inaccurate evidence summaries, and do a terrible job of indexing articles," Petersen writes. This is a critical distinction; the threat isn't just that machines are replacing humans, but that they are flooding the zone with plausible-sounding garbage that can directly impact patient care.

The stakes here are existential. Grinstead notes that while she loves her job, "it's a terrifying time as hospitals lose funding and state-supported conspiracists dress up weird lies as scholarly evidence." Petersen effectively frames the librarian not as a gatekeeper of books, but as a defender of truth in a landscape where bad faith actors and broken algorithms are colluding. The argument holds weight because it moves beyond abstract fears of AI to concrete examples: a bot mis-indexing a study on fluid conservation during a hurricane, or a clinician being unable to distinguish a real citation from a generated one without deep digging.

"For every 'Day in the Life' interview like this we publish on Culture Study, I'm donating $500 to a non-profit organization of the author's choice."

This structural choice by Petersen to highlight the donation underscores the piece's commitment to supporting the very infrastructure of knowledge it describes, even as that infrastructure crumbles. However, critics might argue that focusing on the "fight" against bots distracts from the systemic underfunding of public health information systems that made them vulnerable in the first place. The problem isn't just the bots; it's the lack of resources to verify the data they produce.

The Erosion of Controlled Knowledge

The piece delves into the technical mechanics of how information is organized, revealing a silent degradation of quality. Petersen explains Grinstead's frustration with the shift from human-curated controlled vocabularies to algorithmic tagging. "When I was starting out as a librarian, there were people at the National Library of Medicine who applied these controlled terms to most of what's in PubMed. Now that's all done by algorithms, and the results are pretty terrible," she writes.

This is a profound insight into the hidden costs of automation. The efficiency gains of algorithms come at the price of precision, a trade-off that is acceptable for searching movie titles but dangerous for medical research. Petersen captures the exhaustion of this new reality: "Running a literature search is more complicated, takes longer, and in the end I never feel as confident that I've found everything I need to." The editorial judgment here is sharp: we have optimized for speed and volume, sacrificing the reliability that medical professionals desperately need.

The human element remains irreplaceable. Grinstead explains that while she can flag methodological flaws, she cannot make the final clinical judgment. "I can recognize some basic methodological flaws, possible shadiness of a publisher or author, etc., and at least flag that for the clinician," Petersen notes. This highlights the librarian's role as a translator and verifier, a function that AI currently cannot replicate without risking patient safety. The argument is compelling because it humanizes the data, reminding readers that behind every search query is a potential life-or-death decision.

The Fragility of the Information Ecosystem

Beyond the technical challenges, Petersen explores the emotional toll on the workforce. Grinstead describes a team that has shrunk from fifteen staff to eleven, with some service areas now staffed by a single person. "The threats to healthcare, to hospitals in this country, are just unfathomable and overwhelming," Petersen writes, channeling Grinstead's dread. This section serves as a stark reminder that the quality of information is directly tied to the health of the institutions that manage it.

The piece also touches on the isolation of remote work, noting that while digital tools connect the team, they lack the serendipitous collaboration of in-person interaction. "I no longer spend much time driving from one hospital to another, or getting lost looking for distant conference rooms, or enjoying surprise snacks," Petersen writes. This loss of informal connection is a subtle but significant cost of the modernization of healthcare administration.

"One of my colleagues, when she hears the 'but everything is on the internet' line, responds that it's on the internet because she put it there."

This quote encapsulates the piece's central thesis: the internet is not a self-organizing library; it is a constructed space that requires constant human maintenance. Without the librarians who curate, index, and verify, the internet becomes a chaotic repository of misinformation. Petersen's framing is effective because it challenges the reader's assumption that access equals understanding.

Bottom Line

Anne Helen Petersen's coverage of hospital librarianship is a vital correction to the narrative that technology has solved the problem of information access. The strongest part of the argument is the detailed exposure of how AI-generated errors and algorithmic indexing failures are actively compromising medical research. Its biggest vulnerability is the lack of a clear policy roadmap for how to reverse these trends in a climate of budget cuts. Readers should watch for how healthcare systems respond to the rising tide of AI hallucinations, as the cost of ignoring this issue will be measured in patient outcomes, not just search errors.

In response to my piece on how How I Write Culture Study, I asked readers if they’d want to participate in a series where people from various professions talk about their work lives, explaining how they organize their days and weeks, how they protect their time, when and how they do their work and how and when they attend to their inbox, etc. etc.

Our first entries in the series are from a freelance audiobook narrator, a gardening ceramacist, an engineering grad student, a hairstylist, and a collaborative pianist. Today, you’ll hear about what it’s like work as a hosptial librarian.

If you’d like to volunteer to talk about a day/week in your life for a potential interview — crucially, this work does not have to be for pay; I’d love to hear from caregivers — here’s the very simple sign-up.

Now, let’s hear from Carrie Grinstead about how she deals with AI bot creating trash citations, cleaning up robot work, and how she responds to people who say “but everything’s on the internet.” This one’s so fascinating!

Let’s start with how you described your work to me:

I’m a hospital librarian. I search databases and other sources for information to support nurses, doctors, dietitians, PTs, etc. with any number of tasks -- patient care, research, arguing with insurance companies. These days I also fight with all the AI bots that generate fake citations, spit out inaccurate evidence summaries, and do a terrible job of indexing articles. I work for a large health system and absolutely love my job, but it’s a terrifying time as hospitals lose funding and state-supported conspiracists dress up weird lies as scholarly evidence.

Because people will ask this immediately: how did you get this job?

I had pretty much decided on library school by my senior year of college. I was about to get a degree in history and planned to get an MFA, and I knew I wasn’t resourceful or clever or talented enough to turn either of those things into a job. Then on ...
