⭐What Does Digital Library Mean?
A digital library, unlike other forms of media such as print or microform, is a specialized form of library that encompasses a collection of digital assets. Such digital objects can be in the form of visual material, text, audio or video that are in electronic media forms. As it is a library, it also has features to organize, store and retrieve media or files that make up the collection. Content in a digital library may also be stored locally or accessed by means of networks when stored remotely.

⭐Techopedia Explains Digital Library :-
Digital libraries consist of a collection of digital resources that may have existed only in digital form, or have been converted from another form to digital. These resources are generally stored in a broad range of formats and can be accessed by users over a computer network. Such libraries have many advantages in that they can be updated on a daily basis and can be ac.cessed ins.tantly by users. Ad.ditionally, they do not have a physical boundary, can store more information, and offer access to multiple resources simulta.neously.

⭐Origins
Although the concept of digital libraries has been traced back to nineteenth-century scientific fiction writers such as H. G. Wells, most library historians credit Vannevar Bush's description of the memex in the July 1945 edition of Atlantic Monthly as the original source. Despite being limited to analog technologies such as microfilm that seem crude in the early twenty-first century, Bush anticipated several key features of digital libraries, including rapid and accurate access to scientific and cultural information.

⭐Challenges: Technical And Ethical
The technical challenges confronting librarians, computer scientists, cognitive psychologists, and others working on the frontiers of digital libraries are formidable. These include interoperability (what protocols and standards are needed to ensure that distributed digital libraries will provide widespread interconnected access?), access (what types of user interfaces are most effective in providing easy access to diverse communities of users seeking in.formation for different reasons?), preservation (what technologies are needed to assure the long-term survival of digital information resources?), and sustainability (what financial resources are needed to support the maintenance of digital libraries, and how can they be pro.cured?).
