Digital library

A digital library, also referred to as an online library, an internet library, a digital repository, a library without walls, or a digital collection, is an online database of digital resources that can include text, still images, audio, video, digital documents, or other digital media formats or a library accessible through the internet. Objects can consist of digitized content, such as print or photographs, as well as originally produced digital content, including word processor files or social media posts. In addition to storing content, digital libraries provide mechanisms for the organization, searching, and retrieving of content from the collection. Digital libraries can vary immensely in size and scope, and can be maintained by individuals or organizations. The digital content may be stored locally, or accessed remotely via computer networks. These information retrieval systems are able to exchange information with each other through interoperability and sustainability.
