Walk into any library today and you will likely see someone managing digital databases, guiding students through online journals, or curating e-resources. This is a far cry from the role of a librarian centuries ago. The library and information science (LIS) profession has travelled a remarkable distance, moving from quiet custodians who guarded scrolls to information experts who navigate complex digital systems. Understanding this journey helps us appreciate how librarianship grew into a respected, skill-based profession. The evolution is usually divided into three broad phases: the scholarly period, the vocational period, and the professional period.

The scholarly period: guardians of knowledge
In ancient times, libraries were rare and precious institutions. They were not open to everyone, and the people who managed them were often scholars themselves. These early librarians were seen as custodians of knowledge, responsible for collecting, copying, and preserving valuable texts for future generations. The role of the librarian was closely tied to that of the scholar, and the two identities frequently overlapped.
The most famous example is the Library of Alexandria in Egypt, which flourished under the Ptolemaic dynasty from the 3rd century BCE. At its height it housed somewhere between 40,000 and 400,000 papyrus scrolls and was the leading intellectual centre of the ancient world. It was far more than a storehouse of books. It was conceived as a research institution where great minds could devote themselves entirely to study, writing, and teaching.
Scholars who shaped the role
The head librarians at Alexandria were appointed by the royal court and served for life, and each was a noted scholar who had made an original contribution to a field of knowledge. Many brilliant figures worked there, including Zenodotus, who worked to standardise the texts of Homer, and Callimachus, who compiled the Pinakes, often considered the world’s first library catalogue. Eratosthenes, who once served as chief librarian, calculated the circumference of the Earth with striking accuracy.
This pattern was not limited to the Mediterranean. The Nalanda University library was a celebrated centre of learning that drew scholars from across Asia. These ancient libraries shared a common feature: they treated the management of knowledge as the work of learned individuals, not as a separate, trained occupation. There was no formal qualification for a librarian, no standard methods, and no professional community. Knowledge management was a scholarly duty rather than a defined career.
The vocational period: the rise of structured librarianship
The 19th century marked a major turning point. Library science began to develop in earnest as printed materials multiplied and public libraries spread. The Industrial Revolution increased the demand for education and literacy, and as libraries opened their doors to ordinary people, the casual, scholarly approach of the past was no longer enough.
When collections grew from a few hundred precious texts into thousands of accessible books, the need for systematic organisation became urgent. Readers needed to find materials quickly, and that required consistent rules. This practical pressure pushed librarianship towards becoming a vocation, a structured occupation with its own methods and tools, rather than a scholarly pastime.
Classification and standardisation
This era gave us the classification systems that still anchor library practice. The Dewey Decimal Classification, the Library of Congress Classification, and later the Bliss Bibliographic Classification all emerged to help users navigate expanding collections. These systems turned the organisation of books into a repeatable, teachable skill.
The work of this period has been described as library economy, a procedure-based approach that focused mainly on the practical problems of running a library: how to acquire, arrange, store, and lend materials efficiently. Professional bodies also began to form. The American Library Association was founded in 1876 to connect librarians with one another, signalling that those who managed libraries were beginning to see themselves as a distinct group with shared concerns.
The shift in the librarian’s identity
During this time the role of the librarian started to change in a fundamental way. They were no longer only guardians of rare texts. They became educators and guides, helping the public in their search for knowledge. This was the foundation on which a true profession could later be built, though the work was still seen largely as a set of practical tasks rather than an intellectual discipline.
The professional period: gaining recognition and discipline
The 20th century saw librarianship mature into a genuine profession with academic standing. In the early 1900s, practitioners began to standardise their practices, and librarianship became more professionalised. A profession requires more than routine tasks. It needs a body of theory, formal education, research, and ethical standards. All of these began to take shape during this period.
A key development was the founding of the University of Chicago’s Graduate Library School in the 1920s, which redefined library science as the scientific study of the interaction between books and people. This moved the field away from mere library economy and towards a research-driven discipline. The librarian Pierce Butler argued for the use of quantitative methods and social science ideas to address society’s information needs, marking a clear break from the purely procedural approach of the past.
The Indian contribution: S.R. Ranganathan
No discussion of the professional period is complete without S.R. Ranganathan, widely regarded as the Father of Library Science in India. A mathematician who turned to librarianship, Ranganathan gave the profession both philosophical depth and practical tools. His Five Laws of Library Science (1931) became a widely accepted statement of the ideals of library service, emphasising accessibility, user service, and the dynamic, growing nature of libraries.
His technical contributions were equally important. The Colon Classification (1933) introduced a flexible system that is used in research libraries worldwide and that influenced older systems such as the Dewey Decimal Classification. He also developed the technique of chain indexing for deriving subject entries and produced the Classified Catalogue Code, which moved beyond Anglo-American cataloguing traditions.
Crucially, Ranganathan worked actively to professionalise librarianship through education. He established the first library science school in the country at the University of Madras in 1929, started the first graduate programme in library science at Delhi University in 1948, and later founded the Documentation Research and Training Centre in Bangalore in 1962. These institutions trained generations of professionals and established library science as a respected academic discipline.
From librarianship to information science
As the 20th century progressed, the field broadened. The term documentation evolved into information science, which gained a distinct identity after 1960, focusing on the representation, storage, and retrieval of information. Library science and information science gradually merged into the combined field we now call LIS. This reflected a wider scope: professionals were no longer concerned only with physical books but with information in all its forms.
The digital age: from custodians to digital experts
The most recent chapter of this journey is driven by technology. The growth of computing and the explosion of digital information have caused a paradigm shift, moving librarians from custodians of books to digital curators, educators, and technology specialists. The traditional image of a librarian stamping due dates has been replaced by a professional who manages databases, designs online resources, and guides users through vast digital repositories.
Modern LIS professionals need both traditional and new skills. Alongside cataloguing, classification, and preservation, they now require expertise in data management, digital preservation, instructional design, and information literacy. Many pursue specialised training in digital librarianship and research data curation to stay relevant.
Their work has also spread far beyond library walls. LIS professionals are now employed in academic institutions, corporations, government agencies, and non-profit organisations, where their abilities in information management and research are in growing demand. Emerging fields such as knowledge management, data science, and data analytics are expanding the traditional boundaries of the discipline even further.
One role stands out in this era: promoting digital literacy. In a world flooded with information, librarians help people develop the skills to find, evaluate, and use digital information responsibly. This makes them essential guides through a complex information landscape, ensuring that knowledge remains accessible to all.
Why this journey matters
The evolution from scholarly custodians to vocational organisers to recognised professionals shows a clear pattern. At each stage, the librarian’s role expanded to meet the information needs of society. Ancient scholars preserved knowledge for a privileged few. Vocational librarians organised it for a growing public. Professional librarians built the theory, education, and standards that turned the work into a respected discipline. Today’s digital experts ensure that knowledge thrives in an electronic age.
Through every phase, one mission has remained constant: connecting people with the information they need. The tools have changed from papyrus scrolls to digital platforms, but the underlying purpose of the profession has endured.
What do you think? If ancient librarians were scholars and modern ones are digital experts, what new skills do you think LIS professionals will need a decade from now? And do you believe the rise of artificial intelligence will strengthen the role of the librarian, or challenge it?
