Google, the most successful commercial internet search engine, entered a keyword “digital library” in the
internet, and then Wikipedia and various other sources define “digital library” as a “library in which
collections are stored in digital formats (as opposed to print, microform, or other media) and accessible by
computers.” There are many definitions of a "digital library." Terms such as "electronic library" and "virtual
library" are often used synonymously. The elements that have been identified as common to these definitions
are: Digital Library is a "Collection of digital object (text, video and audio) along with method for access and
retrieval, [as far as users are concerned] and also for selection, organization, and maintenance [1]. Delving into
this definition, the library is an organized body that holds collections – digital objects that have been grouped
into categories, presumably for access purposes. So, a digital Library is an informal collection of information,
stored in digital formats and accessible over a network, together with associated services.
