Librarians built the web's core, and editors still rely on it

The Card Catalog Conspiracy Nobody Noticed

In 1967, while Silicon Valley was still orange groves and IBM was building room-sized computers for corporations, a mild-mannered librarian in Ohio was quietly solving a problem that would accidentally create the blueprint for the modern internet. Jesse Shera was watching American libraries waste millions of dollars on duplicate work. Every time a new book was published, thousands of libraries across the country would independently create identical catalog cards with the same author, title, and subject information. It was like having every McDonald's franchise write their own Big Mac recipe from scratch.

Shera, working at Ohio College Library Center (later renamed OCLC), proposed something radical: What if libraries could share their catalog information? Not just locally, but nationally. Create the card once, use it everywhere. The idea sounds mundane now, but in the 1960s it was genuinely revolutionary. Libraries had operated as isolated information islands for centuries. Shera was essentially proposing to network them into a single, searchable database decades before anyone used the word "database" in casual conversation. His colleagues thought he was dreaming.

The technical challenges seemed insurmountable. How do you connect libraries in Ohio to libraries in California when long-distance phone calls cost a fortune and computer networks existed mainly in science fiction? Shera's solution was elegantly simple: Build a central computer system that libraries could dial into using regular phone lines. Libraries would contribute their catalog information to the shared database and could search everyone else's contributions in return. Sound familiar? It should. Shera had just described client-server architecture, distributed databases, and networked information sharing the fundamental concepts that would later power the World Wide Web.

The first OCLC terminal went online in 1971, connecting Ohio State University's library to the central computer. Within months, libraries across Ohio were joining the network. By 1973, institutions in other states were clamoring to connect. The network effect kicked in with a vengeance. As more libraries joined OCLC, the shared database became exponentially more valuable. Soon, libraries weren't just sharing catalog cards they were coordinating interlibrary loans, tracking which institutions owned which books, and enabling patrons to request materials from anywhere in the country.

Shera had accidentally created something much bigger than a catalog-sharing service. He'd built the world's first large-scale information network, connecting thousands of institutions across multiple countries into a single, searchable knowledge base.

The Man Who Saw the Whole World as One Library

Frederick Gridley Kilgour born in Springfield, Massachusetts in 1914 had spent his early career building a quiet reputation as a rigorous empiricist. He earned a bachelor's degree in chemistry from Harvard College in 1935, then held a position as assistant to the director of Harvard University Library. During World War II, he served as Executive Secretary and Acting Chairman of the United States government's Interdepartmental Committee for the Acquisition of Foreign Publications, an organization of 150 persons in outposts around the world that microfilmed newspapers and intelligence items and sent them back to Washington. He received the Legion of Merit for this intelligence work in 1945.

After the war, Kilgour worked at the United States Department of State as deputy director of the Office of Intelligence Collection and Dissemination, then was named Librarian of Yale Medical Library in 1948. At Yale, he was also a lecturer in the history of science and technology. While running Yale University Medical Library, he began publishing studies on library use and effectiveness. He asked his staff to collect empirical data use of books and journals by categories of borrowers to guide selection and retention of titles. He viewed the library "not merely as a depository of knowledge," but as "an instrument of education."

At the dawn of library automation in the early 1970s, Kilgour joined the Ohio College Association to develop OCLC and led the creation of a library network that today links 55,000 institutions in 110 countries. He implemented his vision by developing OCLC (originally started as the Ohio College Library Center, later developed into Online Computer Library Center), the first and largest library network system.

In 1971, Kilgour created WorldCat, the online union catalog, where one original cataloging by one library is shared by all other libraries in the world, eliminating repetitious original cataloging practices. The concept was elegant in its generosity: each participating library contributed cataloging work once, and that contribution immediately benefited every other library in the network. Redundancy became collaboration. Isolation became interconnection. The cost savings were immediate and enormous, but the deeper transformation was philosophical a profession that had operated as independent collectors for centuries suddenly became a cooperative enterprise.

By 1979, OCLC connected over 2,000 libraries. Today, it links more than 72,000 libraries in 170 countries. Every time a reader searches their local library's catalog, they are tapping into a shared resource that traces its conceptual ancestry to Kilgour's vision of a world where information infrastructure was built collectively, not redundantly.

The Teen Who Refused to Accept "Good Enough"

While Kilgour and Shera were networking libraries in Ohio, a different kind of reading system was quietly transforming access for an entirely different population. Louis Braille went blind due to an accident that resulted in injury to one eye while infection befell the other not long after. He joined what was reportedly one of the earliest institutions in the world specifically designed for blind children: the Royal Institute for Blind Youth in Paris.

The reading technique used there was extremely difficult and inconvenient, requiring large volumes of books with large-print text to be laboriously traced by students' fingers. Everything seemed so different after Louis Braille discovered "night writing," a form of communication created by Charles Barbier, a French army officer. Barbier developed a method for soldiers to read messages without using any light, creating dots on paper and reading by touch. As explained by the American Foundation for the Blind, Barbier showed his invention at the institute in Paris in the early 1820s, and the system immediately captivated the young Braille.

At just fifteen years old, Louis Braille began transforming Barbier's military night code into something fingers could read rapidly. The military system used twelve dots arranged in a grid too complex for quick tactile reading. Braille simplified it to six dots, creating a system with sixty-three possible combinations. What had been a cumbersome military cipher became an elegant, portable reading alphabet that could fit in the palm of a hand. The tactile script he developed allowed independent literacy. Despite initial resistance, Braille's system became a global standard, empowering blind individuals worldwide and changing education and accessibility forever. This innovation originated from a young blind teenager's personal need and his refusal to accept that "good enough" was good enough.

The Dreamer Who Named What Came Next

On August 24, 1965, Theodor Nelson presented a paper to the Association for Computing Machinery national conference in which he introduced the word "hypertext" to refer to "a body of written or pictorial material interconnected in such a complex way that it could not conveniently be presented or represented on paper." Nelson, who had started musing about this sort of associative thinking and linking as a Harvard University graduate student in 1960, viewed hypertext as an integral part of an imagined globally interconnected library and publishing system that would "grow indefinitely, gradually including more and more of the world's written knowledge" and "have every feature a novelist or absent-minded professor could want, holding everything he wanted in just the complicated way he wanted it held, and handling notes and manuscripts in as subtle and complex ways as he wanted them handled."

Two years later, while working at the publisher Harcourt Brace, Nelson started describing his global library as "Xanadu." "For forty years," Nelson wrote recently, "Project Xanadu has had as its purpose to build a deep-reach electronic literary system for worldwide use and a differently-organized general system of data management."

Nelson's grand vision of a universal library and publishing system came in for its share of derision. In 1995, a Wired magazine writer devoted twenty thousand words to detailing what he called "The Curse of Xanadu," calling it "the longest-running vaporware project in the history of computing a 30-year saga." Nelson responded angrily, but he has also hinted that he views Xanadu as an impossible dream. He took the word from the imaginary home of Kubla Khan in Samuel Taylor Coleridge's uncompleted poem; Orson Welles used the same word for Citizen Kane's extravagant, uncompleted mansion.

And yet, just five years after that obituary for Xanadu, the dream of a universal hypertextual library seemed less like the fantasies of Ted Nelson than a description of a multibillion-dollar industry called the World Wide Web. Even those whose professional calling required thinking soberly about the distant past needed to consider whether such a contemporary development would reshape the ways people research, teach, and write history.

The Wikipedia Classroom and the Next Generation

In 2015, Saul Hoffman, a student at Ca' Foscari University of Venice, was deep into research on how Wikipedia could be used as a tool to boost critical thinking, collaborative skills, and research abilities among students. He organized a Wikipedia editing event and invited educators and librarians to join. One of the attendees was Loretta, a librarian with 30 years of experience, and expertise in electronic resources, institutional repositories, and information literacy courses for students.

Inspired, Loretta began weaving Wikipedia into her bibliographic research courses. Her focus was on articles on topics overlooked or not well developed in Italian Wikipedia Japanese theatre, multicultural London, and more. She also organized events centered on women's biographies and cultural themes, such as Virginia Woolf's Three Guineas, women writers of crime fiction, and artists from Japan's Edo period. Her students worked on individual Wikipedia contributions as part of their assignments.

Over the course of three years, 317 students participated in those activities and over 400 articles were added to Wikipedia. Something else started to shift: the academic view of Wikipedia began to change. "Thanks to these courses, the 'reputation' of Wikipedia also improved over time on an academic level," Loretta notes. "Several professors were involved and offered this training activity to their students as a certified internship."

"I am pleased to have given many students the opportunity to get to know Wikipedia and how it works. To shift from passive readers to active, shared approach to the production and use of knowledge, placing research, selection, and the use of reliable sources at the center of this work," she reflects. Her commitment continued even after reaching retirement, extending collaboration to other schools and institutions in northern and central Italy, and eventually the University of Roma Tre, where students are working on a wikibook on the History of Italian Feminism.

To date, Loretta has authored 164 Wikipedia articles on topics ranging from the anti-Nazi cabarets in Munich in the 1930s to Burmese women writers, from ancient Japanese nomadic puppeteers to the Querelle des femmes. "I don't like collecting edits," she says, "I prefer to build something that stays."

What This Means for ArticleSelected Readers

Independent editors working today operate in an ecosystem that owes more than they may realize to the librarian's instinct for shared infrastructure. The citation management tools, the collaborative writing platforms, the style guides that standardize how information is presented across publications all of these trace lineage to the moment when Shera proposed that libraries stop duplicating work and start sharing it.

The reading system now used by independent editors worldwide is not any single software or standard. It is a disposition: the belief that building something collaboratively, then sharing the benefits of that building freely, creates more value than each editor working in isolation. This is the librarian's gift to the information economy.

For editors researching practitioners, frameworks, and ideas, understanding this lineage offers practical clarity. When you use a shared citation database, you are participating in a system designed by people who believed that eliminating redundancy was more important than protecting individual ownership of cataloging work. When you follow a standardized editorial style, you are contributing to a shared infrastructure that makes your work legible to others in your field. The reading system is not just a tool it is a philosophy of information access, and it was built by librarians who thought the network mattered more than any single node in it.

Where the Story Leads Next

The thread that connects Braille's tactile alphabet to Nelson's hypertext vision to Loretta's Wikipedia pedagogy is not just technological. It is ethical. Each system began with a single person's recognition that access to information should not require each person to build their own copy of everything. The librarian's insight was structural before it was digital: shared infrastructure reduces waste, multiplies access, and creates conditions for collaboration that isolated work cannot achieve.

Independent editors today inherit this infrastructure. They swim in waters shaped by Kilgour's insistence that one cataloging effort should benefit every library, by Shera's conviction that networked information beats isolated information, by Nelson's decades-long faith that hypertext would eventually arrive, and by Loretta's daily practice of bringing students into collaborative knowledge-making. The reading system is not a product. It is a posture: the belief that good information should be easy to find, read, cite, and build upon.

Whether that posture survives the pressures of platform fragmentation, paywall proliferation, and algorithmic curation remains an open question. But for now, the infrastructure stands. And every time an editor opens a shared citation database, follows a standardized style guide, or links to a Wikipedia article, they are extending a tradition that began with a librarian who wanted to stop buying the same catalog cards over and over again.
