Digital libraries are online collections of digital resources, such as books, articles, images, and videos. They provide users with easy access to a vast array of information from anywhere with an internet connection. Digital libraries often include tools for searching and organizing content, making it simpler for users to find what they need. Many digital libraries are created by institutions like universities, public libraries, and organizations such as the Library of Congress. They may offer free access to materials or require a subscription. Digital libraries play a crucial role in preserving knowledge and promoting literacy in the digital age.
