A digital library is a collection of digital resources, like books, audio, and video, accessible electronically. It's essentially a library that operates online, offering access to information through computers and other devices with an internet connection. 

Here's a more detailed explanation:

• Accessibility:

  The main advantage of a digital library is its accessibility. Users can access its contents from anywhere with an internet connection, eliminating the need for physical visits or storage. 

• Organization and Retrieval:

  Digital libraries also provide means for organizing, storing, and retrieving the digital objects they hold, much like traditional libraries. 

• Similar Services to Traditional Libraries:

  While online, digital libraries offer services similar to traditional libraries, such as selection, acquisition, cataloging, reference, and preservation of digital content. 

• Evolution from Traditional Libraries:

  A digital library can be seen as an evolution of traditional libraries, adapting to the digital age and providing access to information in a new way. 

• Digital Objects:

  Digital libraries contain digital objects, which can include text, images, audio, and video, all stored in electronic formats.
