The English word librarian comes from the Latin librarius, "of books" — but the job is older than books. The first people paid to keep and organize recorded knowledge worked with clay: the scholars of King Ashurbanipal's library at Nineveh, in the seventh century BCE, arranged some 30,000 tablets and fragments by subject and closed them with written curses on anyone who would steal or erase them. Every catalog, classification scheme and reading room since is a refinement of what they were doing.

The work has never really been about reading books all day. It is about building a collection with a purpose, describing every item so that a stranger can find it, and — hardest of all — turning a visitor's half-formed question into the question they actually needed answered. The route in varies sharply by country: a master's degree in North America, a chartered professional portfolio in Britain, a competitive state examination in France, a salaried two-year traineeship in Germany.

This page follows the profession from Nineveh and the Pinakes of Alexandria through al-Qarawiyyin, Panizzi's Round Reading Room and the trade's modern birth in 1876, to a present in which circulation and cataloging are largely automated while librarians defend collections in courtrooms and teach readers to navigate misinformation. It covers how people enter the work today, what the craft actually consists of, who reached the top of it, and how much of it a machine can take.

How exposed is it to AI?

45 / 100

Moderate

Close to half of the traditional task list — circulation, copy cataloging, ready-reference lookup, purchase prediction — is already automated or realistically automatable. What remains is the judgment layer: negotiating what a person actually needs, deciding what a community's collection should hold and defending that decision publicly, teaching source evaluation, and stewarding unique local material no database holds. Those tasks resist automation not because machines lack skill but because they are exercises in trust and accountability.

Seven ways into this profession

Frequently asked questions

Do you need a degree to become a librarian?
In most countries, yes, though the shape differs. The United States and Canada expect a master's degree in library and information science accredited by the American Library Association. The UK accepts an accredited degree plus CILIP professional registration. France recruits its senior librarians through a competitive state examination, and Germany trains academic librarians in a salaried two-year Referendariat after a subject degree.
What do librarians actually do all day?
Far less shelving than the stereotype suggests. A working day mixes reference questions, teaching sessions or children's programs, selecting and weeding the collection, fixing metadata, managing e-lending platforms and negotiating with vendors. In academic libraries much of the work is teaching research skills and managing data; in public libraries a growing share is frontline social work — helping people with forms, jobs and services.
How long does it take to become a librarian?
Typically five to seven years after leaving school: a bachelor's degree in any subject, then a one- to two-year graduate library qualification, then an entry-level professional post. Countries with examination or traineeship systems, such as France and Germany, add a further one to two salaried years. Many librarians qualify part-time while already working in a library as an assistant.
How much do librarians earn?
Modestly for a master's-level profession. The US median was around $65,000 in 2024 according to the Bureau of Labor Statistics; qualified librarians in the UK commonly earn £26,000–£40,000, German public-service scales pay roughly €45,000–€60,000, and Australian mid-career librarians around A$80,000–90,000. Directors of large urban systems can earn well into six figures, but the profession's ceiling is far lower than its education suggests.
Will AI replace librarians?
It is already absorbing parts of the job — routine lookup questions, copy cataloging, circulation — a process that began with search engines in the 1990s, not with chatbots. What resists automation is the rest: negotiating what a person actually needs, teaching people to evaluate sources, judgment over what a community's collection should hold, and the legal and ethical defense of access and privacy.
What is the difference between a librarian and an archivist?
A librarian manages published material that usually exists in many copies and is organized for broad access; an archivist manages unique, unpublished records — letters, ledgers, photographs, institutional files — organized to preserve their original order and context. Training overlaps and many people hold both roles, but the core question differs: librarians ask how readers will find things, archivists ask how the record's integrity survives.
Do libraries still use the Dewey Decimal System?
Most public and school libraries do: OCLC, which maintains the scheme, reports it is used in libraries in more than 135 countries. Large academic and research libraries mostly use the Library of Congress Classification instead, and much of Europe uses the Universal Decimal Classification. A minority of public libraries have dropped Dewey for bookstore-style subject groupings to make browsing easier.
Are libraries dying in the internet age?
Usage has shifted rather than vanished. Britain lost almost 800 public libraries or handed them to volunteers between 2010 and 2019 under austerity, while Finland opened Helsinki's Oodi in 2018 and drew over three million visits in its first year. Digital lending, program attendance and use of libraries as workspaces have grown; what has genuinely declined is the routine factual question the web now answers.
