Introduction Digital Libraries have become the source of information sharing across the globe for education, research and knowledge. The full potential of the Digital Libraries is realized when any citizen can have access to all human knowledge from any location. In today’s scenario the multimedia has become an effective information sharing resource, people of all ages can understand more clearly by seeing / hearing rather than reading. Based on the tremendous growth in the various technologies, the establishment of Multimedia Digital Libraries is not an impossible task. But there are some critical challenges like performance and scalability, that prevail in the Multimedia Digital Library. msccomputerscience.com
Definition Today more emphasis is given to the information captured in the form of Images, Video and Audio. These huge collections of Images, Audio and Video form the Multimedia Information Store best known as Multimedia Digital Library (MDL). msccomputerscience.com
Basic problems addressed Creating means & ways for dealing with & using human knowledge records in the new digitalized AND networked world How to deal with electronic “books”, journals, publications, texts, images, sounds,? create, organize, represent, store, interact, preserve? What access & services to provide? How to effect use? Communities? AND all in a networked environment? msccomputerscience.com
Problems... Problems are technical, organizational, operational managerial, institutional social, legal, economic, cultural … Creating a new world for libraries and for organization, access, preservation & use of human knowledge records in all formats Digital revolution may be as far reaching as that created by Gutenberg & the printed book. msccomputerscience.com
What is a DIGITAL LIBRARY? No single, all-encompassing answer Several perspectives from different communities - different agendas Little communication among them Coherent, integrating concept, approach not yet emerged Complex problems in any approach Many experiments; many experts & “experts” Highly exiting & volatile area msccomputerscience.com
Library perspective “Digital libraries are organizations that provide the resources, including the specialized staff, to select, structure, offer intellectual access to, interpret, distribute, preserve the integrity of, and ensure the persistence over time of collections of digital works so that they are readily and economically available for use by a defined community or set of communities.” msccomputerscience.com
Libraries and information science Concentrates on institutions, service, practice logical extension of libraries Content, collection centered Creation of digital collections - variety of forms Subscription, licensing, sharing of digital resources Organization, representation, storing Access to collections Guided by service mission various environments, user communities various degrees of integration - hybrid libraries msccomputerscience.com
Digital libraries & organizations Variety of organizations built digital libraries scientific & technical societies various fields, academic units projects - institutions, consortia government agencies, international organizations Concentrate on applications & access Availability of collections in different fields New forms of publishing, housing & distribution Generally aimed at services to their communities or perceived needs msccomputerscience.com
Problems for libraries Integration between print and digital mixing new digital technology with print, local with global; managing diverse resources - all difficult economic trade-off decisions; new economic relations Competition for scarce resources sharpening Institutional, cultural & social adjustments not easy Bridging the digital divide Resistance, threats: msccomputerscience.com
