Directory of Digital Libraries

Are you a student, researcher, educator, or someone interested in huge online repositories of text, software, visual media, movies, images, and others? Are you looking for information that might help you with your research or homework? If so, you need the services of a digital library.

Welcome to the Directory of Digital Libraries. We are a one-stop source of information about digital libraries and our mission is to guide you to the best of them.

Let us start with some basic information about digital libraries.

Definitions of Digital Libraries

Digital libraries have many other names—virtual libraries, electronic libraries, hybrid libraries, libraries without walls, digital collections, digital repositories, and so on.

The concept of digital libraries being brand new, people don’t agree with what exactly is a digital library. So there are multiple definitions, descriptions, and explanations of the same.

Here is the Digital Library Federation’s definition: “Digital libraries are organizations that provide the resources, including the specialized staff, to select, structure, offer intellectual access to, interpret, distribute, preserve the integrity of, and ensure the persistence over time of collections of digital works so that they are readily and economically available for use by a defined community or set of communities.”

We are aware that the above definition sounds complicated. So let us simplify it. A digital library is an online collection of digital objects such as images, video, audio, text, documents, and others.

If you explore a digital library, you will come across documents, photographs, text, images, infographics, movies, eBooks, and so on. Digital libraries not only store such content, but also make it easy for users to organize, search, and retrieve the required content.

Any individual or organization can own and manage a digital library. They can store and maintain digital content on local servers, but allow you to access the content remotely via a network of computers.

Types of Digital Libraries

There are three major types of digital libraries.

National Libraries – The copyright laws of most countries dictate that a copy of every work published within the borders of the country has to be preserved in an institution, usually the national library.

With the advent of the Internet, these laws were later amended to include electronic documents. Today, all countries have electronic depositories, in which copies of all digital works produced are carefully preserved and made easy to access.

Digital Archives – An archive is not the same as a library. While libraries store secondary sources of information such as books and periodicals, archives store primary sources of information such as papers and letters produced by organizations and individuals.

Digital versions of archives, called online archives or digital archives, store primary sources. The Oxford Text Archive is considered to be the oldest digital archive.

Institutional Repositories – These are digital libraries of an institution’s papers, books, theses, and other works that can be converted into digital form.

Features of a Digital Library

As you already know, there are differences between a physical library and a digital library.

  • Physical libraries are limited by space, but digital libraries are unlimited.
  • As digital information doesn’t occupy space, one can store unlimited information in digital libraries.
  • As digital libraries are not physical, the cost of maintaining them is much lower.
  • On the other hand, physical libraries have to spend a lot of money on maintenance, purchase of more books, rent, staff, and so on.

Know the main features of a digital library:

  • Accessible and available round the clock
  • Multiple individuals or institutions can use a digital resource simultaneously
  • Easy and quick access to digital resources
  • No physical boundary
  • Quality of digital content can be improved
  • One can add continuously to a digital library
  • Digital content is easier to store, preserve, and conserve

World Digital Library

The World Digital Library (WDL) was established in 2009 owing to the collaborative efforts of the US Library of Congress and UNESCO. A large number of archives, libraries, museums, international organizations, and educational institutions from all over the world contribute to its growth and development.

The WDL collects and preserves digital material that makes it easy to study, discover, and enjoy historical documents and cultural treasures such as manuscripts, books, newspapers, maps, prints, journals, photographs, prints, films, and sound recordings. The library presents manuscripts, books, maps, and other primary sources of information in 100+ languages, including many endangered and less known languages. Use the search bar on the WDL homepage to search 19,147 items from 193 countries, dating between 8000 BCE and 2000.

Here are the most unique features of the WDL:

  • In addition to a huge body of secular digital works, the WDL preserves several sacred books from the greatest religions across the world. Its collection of Bibles is widely known for its quality and variety of print editions and manuscripts, and languages. Several institutions across the Middle East, North America, Africa, and Europe have contributed to this collection.
  • In December 2012, the Carnegie Corporation, which is based in New York, permitted the Library of Congress to digitalize its collections on Afghanistan and make its content freely accessible on the WDL
  • The WDL preserves several books, manuscripts, maps, and other documents that bear the significance of being the “first” in the histories of particular countries, linguistic areas, or cultures. These documents include the following:
    • Oldest surviving copies of important literary or historical works
    • First editions of noteworthy books
