                     ii.  Digital libraries are not bound to physical spaces. Different components of digital
                        library may be distributed to different locations that works coherently so as to meet
                        the requirement of users;

                    iii.  Requirement  of physical spaces in digital environment reduces essentially  for i)
                        housing servers for hosting digital content; ii) PCs as clients for accessing digital
                        content; and iii) staff for maintaining digital libraries.

                    iv.  A digital library owns and controls the information, it provides access to
                        information, not just a pointer to it;

                     v.  A digital library has a  unified organizational structure with consistent points for
                        accessing the data;

                    vi.  A digital library is not a single entity, it may also provide access to digital material
                        and resources from outside the actual confines of any one digital library;

                   vii.  Digital libraries support quick and efficient access to a large number of distributed
                        but interlinked information sources that are seamlessly integrated;

                   viii.  Digital libraries offers access to its content to multiple users simultaneously, these
                        content can be listed in multiple ways by different users simultaneously;

                    ix.  Digital libraries have collections that i) are large and persist over time; ii) are well-
                        organized and managed; iii) contain many formats; iv) contain objects and not just
                        their representations; v) contain objects that may be otherwise unobtainable; and vi)
                        contain some objects that are digital ab origine; and

                     x.  Digital libraries include all the processes and services offered by traditional libraries
                        though these processes will have to be revised to accommodate difference between
                        digital and paper media.

                   5.  World Wide Web (WWW) V/s Digital Library

                   The World Wide Web (WWW) or the Web is a collection of thousands and thousands of
                   documents and is considered as a digital library by many people. The web is means by
                   which most digital libraries are accessed, but it is not a digital library itself although it
                   has several features of a digital library. The web, unlike a digital library, is a unorganized
                   collection of documents, many of them ephemeral information which does not have any
                   durability or lasting value. Most search engines hunt down their holdings from web sites
                   distributed  across the web  space,  whereas digital libraries are generally  more tightly
                   controlled, and have a targeted customer set.

                   Today’s digital libraries are built around  Internet and  web technologies. While the
                   Internet serves as  the carrier and provides the  contents delivery mechanism, the web
                   provides the tools and techniques for content publishing, hosting and  accessing. The
                        5
