Most students today reach for a search engine before they reach for a library shelf. That single habit reveals how central the World Wide Web has become to the way we find, organise, and use information. Yet the web is often confused with the internet itself. The internet is the underlying network of connected computers, while the web is the system of interlinked documents and resources that sits on top of it. Understanding why the web matters, and how it reshaped libraries in particular, helps explain why information access has never been faster or more democratic than it is now.

How the web organises information
The World Wide Web is the leading information retrieval service of the internet, giving users access to a vast collection of content connected through electronic links. It was developed beginning in 1989 by Tim Berners-Lee and his colleagues at CERN, the international scientific organisation based in Geneva. Before the web, network protocols were special-purpose tools that handled narrow tasks. The web changed this by becoming a single, versatile space where any person or group with network access could share media-rich information with others.
What makes this possible is a small set of standards working together. A document is written in HyperText Markup Language (HTML), which defines the structure of a web page, such as its headings, paragraphs, and tables. Each document is given an address called a Uniform Resource Locator (URL). The document is then transferred between computers using the HyperText Transfer Protocol (HTTP). A web browser interprets the HTML and displays the page in a layout suited to the screen. These standards are maintained by neutral bodies such as the World Wide Web Consortium, which keeps the web open rather than controlled by any single company.
This standardisation is the quiet reason the web is so powerful for organising information. Because every resource has a unique address and a common format, content created by a government department, a university, a newspaper, and a hobbyist can all coexist in the same space and be reached the same way. The web does not store information in one giant central file. Instead it links scattered pieces together into a structure that anyone can navigate.
Integrating different media and systems
The early proposal at CERN noted there was no reason hypertext links could not also connect multimedia documents, including graphics, speech, and video. That single observation is why the web feels so different from a printed encyclopedia. A web page can hold text, an embedded image, an audio clip, a chart, and a video, all rendered together as one coherent page. The web therefore acts as an integrating layer that pulls together formats which once required separate devices and separate skills to use.
This integration extends to information systems as well as media types. A library catalogue, a bank’s account portal, a railway reservation system, and a university results page can all be exposed through the web using the same browser. For the user this means one familiar tool unlocks dozens of underlying databases. The web does not replace these systems; it provides a common doorway to them.
Multimedia and hypertext: the engine of retrieval
Two features explain why finding information on the web is both efficient and engaging: hypertext and multimedia. Hypertext is a system that creates a branching or network structure, allowing direct jumps to related information. When you select a highlighted word or phrase, you are taken to another document that adds detail to that term. Hypertext links are usually shown by highlighting a word in a different colour, and selecting one can call up a definition, a related page, or associated multimedia.
The significance of hypertext is that it mirrors the way people actually think. Human curiosity rarely moves in a straight line. A reader exploring a topic naturally wants to follow side questions, check a source, or compare a related idea. Hypertext supports this non-linear movement. Instead of reading a single document from start to finish, you can follow a trail of connected resources, each one expanding on the last. This is fundamentally different from a printed book, where cross-references demand that you physically locate another volume.
Why multimedia matters for understanding
Multimedia adds a second dimension to retrieval. Hypermedia documents feature links to images, sounds, animations, and movies, not just text. This matters because different ideas are best communicated through different formats. A surgical procedure is clearer in video than in prose. A piece of classical music must be heard. A geographic distribution is easier to grasp on an interactive map than in a table of figures.
For learning, this combination is powerful. When a concept is explained in text and reinforced with a diagram or a short video, comprehension and retention tend to improve. The web allows a single resource to deliver all of these together, which is why online tutorials, explainer videos, and interactive simulations have become standard study tools. The efficiency comes not only from speed of access but from matching the format to the message.
Applications of the web in libraries
Few institutions have been reshaped by the web as deeply as libraries. The traditional library was bound by physical space, fixed opening hours, and the requirement to be present in person. The web removed all three limits. A library can now serve users at midnight, from a hostel room, or from a village hundreds of kilometres away, all through a browser.
Online catalogues and the Web OPAC
The most visible change is the catalogue. The Online Public Access Catalogue (OPAC) is a database of a library’s holdings, listing books, journals, theses, and non-book materials. The web turned this into the Web OPAC, which uses web protocols to make the catalogue reachable on the internet around the clock from anywhere in the world. A user can search by author, title, subject, or keyword, check whether an item is available, and locate it on the shelf, all before setting foot in the building.
Indian libraries have adopted this widely. The Delhi University Library System, one of the largest academic library systems in the country with 34 libraries, offers a centralised Web OPAC to serve information needs across disciplines. The Indira Gandhi National Centre for the Arts provides public access to its catalogue records online while also linking to other relevant resources. These examples show how the Web OPAC has become the standard window into a library’s collection rather than an optional extra.
Access to databases, journals, and e-resources
Beyond the catalogue, the web gives libraries a way to deliver content they do not physically own. As electronic publishing grew, the Web OPAC expanded to provide access to hybrid collections that combine print and digital resources. A student can move from a catalogue entry straight to a full-text journal article, an e-book, or a bibliographic database, all within the same session.
In India, this is organised largely through national consortia. The INFLIBNET Centre operates e-ShodhSindhu, a consortium formed in December 2015 by merging three earlier initiatives, to provide affordable access to electronic resources for universities, colleges, and technical institutions. It offers current and archival access to thousands of core and peer-reviewed journals along with bibliographic and factual databases. Its college component, N-LIST, extends access to thousands of journals and a large collection of e-books to colleges across the country, including access to e-books through the National Digital Library.
This consortium model demonstrates the web’s role in widening access. A single small college cannot afford to subscribe individually to thousands of expensive journals. By pooling demand and delivering content over the web, a consortium negotiates lower rates and shares resources across institutions. The result narrows the gap between well-funded and poorly-funded libraries, helping to address the digital divide in higher education.
Digital archives and remote services
The web also lets libraries preserve and share materials that were once locked away. Digital archives, virtual exhibitions, and digitised rare books and manuscripts can be made available to remote users, protecting fragile originals while widening access. Many academic libraries add video tutorials and guides on how to use their resources, making the library easier to navigate for new students. Remote access tools such as VPNs, proxy servers, and federated login systems allow a registered user to reach subscription resources from off campus, effectively extending the library to wherever the user happens to be.
The bigger picture
Taken together, these features explain why the web is essential for information access rather than merely convenient. It standardises how information is organised so that diverse sources can be reached the same way. It uses hypertext and multimedia to make retrieval both fast and meaningful. And it gives libraries the means to extend their collections far beyond their walls. For a generation of students who expect information on demand, the web is not just a tool sitting alongside the library. In many practical ways, it has become the library’s front door.
What do you think? If most academic resources are now reachable through the web, what unique role should the physical library building continue to play on campus? And as hypertext lets us jump endlessly between linked pages, do you think this freedom helps us learn more deeply or simply makes our attention more scattered?
