It also reflects cultural heritage besides providing archive and generating many research issues pertaining to Natural Language Processing” Digital Library ? Sun Microsystems defines a digital library as the electronic extension of functions users typically perform and the resources they access in a traditional library. These information resources can be translated into digital form, stored in multimedia repositories, and made available through Web-based services. According to other definition 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 available for use by a defined community or set of communities”. What is Digital library ? A Service? An Architecture? A set of Information Resources? A set of tools to locate, search, retrieve information? Possibly the tools to create such resources and services also fall within the purview of DLs Digital face of traditional libraries Include both digital collections and traditional Backbone and nervous system of libraries. Digital library Vs traditional library •Efficient & qualitative services by collecting, organizing, disseminating, retrieving and preserving the information. storing, •Preservation benefits besides making information retrieval & delivery more comfortable. •Online access to historical and cultural documents whose existence is endangered due to physical decay. Digital libraries necessarily include a strong focus on the management of digital content, just as traditional libraries have focused for long on the management of content in physical forms. Digital Content Management Most of the digital content that is being managed includes: • Human Language, in various forms character-coded electronic text, scanned images, printed or handwritten text or human speech. • Language technology helps in managing digital content • Management through learning from past experience also adds to manage content The major areas for great exploitation are: • Information retrieval, • multimedia, • database, • data mining, • data warehouse, • on-line information repositories, • image processing, hypertext, • World Wide Web and wide area information services (WAIS). Few advantages of digital libraries • Access anywhere • Reducing delays • Distributed storage – central access • Better cataloguing • Cross references to other documents • Full text search • Protected information source • Wide exploration and exploitation of the information The information explosion, the wide bandwidth data networks and the potential of Internet-based technologies - such as the Web - make digital libraries one of the important application areas of computer science. Process of Digital Preservation Centralized Server XML Meta File Creation using Dublin core Std. Book scanning status Reject the Book Yes No Scanned Image in TIFF format S/w to divide even & odd pages Conversion to TXT/RTF/HTML Uploading Batch cropping & Cleaning OCR Goals of DL Focused on digitization technology, metadata schemes, data management techniques, and digital preservation. Second-generation digital library exploring new opportunities and developing new competencies. Third-generation digital library focusing instead on fully integrating digital material into the library’s collections through a modular systems architecture. Ingredients for DLs Hardware The minimum machinery to do the job Software The programs for handling data Digital Objects Articles, Conference Papers, Thesis,…… Basic Skills Things one has to learn Hardware A Server You’ll need access to a web server A good PC Scanners Flatbed – Auto feed, Back to back MF Book Scanner Software Open Source Software (OSS) Dspace, E-Prints, Fedora, GSDL…… Proprietary software you can’t avoid Image Editing and Optical Character Recognition Software have to be purchased Content is King The information content is more important than the systems used for its storage, management and retrieval Objects should not be “locked” in specific DLs or archives Creating DLs … Six steps Selecting Acquiring Digitization Creation Of Meta Data Organizing Archiving Providing Access Possible Delivery Formats Pure image formats: TIFF, JPEG Open encoded formats: XML, HTML, ASCII, and Unicode Hybrid formats: PDF, DjVu – can contain both image and text Proprietary formats: Microsoft Word, WordPerfect Digitization: Issues Copyright Access copy and archive copy File size Storage media( CD, Hard disc…) File format ( TIFF,JPEG…) Challenges in Digitization Building digital collections of national importance from existing texts, documents, images . . . Creating new digital documents & linking them Subject portals: Selecting and maintaining open source digital resources Developing / adapting management tools for digital collections Providing access to digital collections 25 Challenges.. Integrating digital & other library collections incl. integration of OPACs, subscribed e-resources and subject portals Establishing services for digital libraries online access & offline support education & training of users and librarians Addressing social, legal, policy issues 26 Challenges in Publishing Preservation of layout Searchability of content and metadata Efficient image compression Easy browsing of books Accommodating low bandwidth user Multilingual text support Multipaging Digital Library Support in India Funding Ministry of Communication & Information Technology (MIT) Ministry of Human Resource Development (MHRD) Manuscript Mission of India Department of Scientific & Industrial Research (DSIRTRP) All India Council for Technical Education (AICTE) University Grants Commission (UGC) Digital Library Initiatives in India Library Consortium in India Scholarly Science Journals Theses & Dissertations Institutional E-Print Archives Books (out of copyright) Manuscripts Newspapers Online Courseware Open Access at Metadata Level Portal and Gateway Services 29 Government of India Min. of C&IT Universal Digital Library Min of Culture National Manuscript Library Others CSIR E-Journals Consortium INDEST-AICTE Consortium UGC Infonet Consortium FORSA Consortium IIM Libraries Consortium Participating centers of DLI PTU-1 PTU-2 PTU-3 Rashtrapathi Bhavan CDAC Noida ERNET IIIT-Allahabad Digital Library of India CDAC Kolkata MIDC Pune University IIIT-H State & City Central Library University of Hyderabad Goa University IISc TTD Tirupati Sringeri Mutt IISc, IIAP, ASR Melkote PoornaPragya AKCE Anna University Kanchi Mutt SASTRA Mega Scanning Centres at IIITH, IIITA CDAC- Noida and Kolkatta Digital Library Initiatives in India Some Examples Digital Library of India http://www.dli.ernet.in/ April 20, 2009 Workshop on Institutional Repositories 33 http://www.ias.ac.in/ April 20, 2009 Workshop on Institutional Repositories 35 http://www.insa.ac.in/ April 20, 2009 Workshop on Institutional Repositories 36 http://medind.nic.in/ April 20, 2009 Workshop on Institutional Repositories 37 April 20, 2009 Workshop on Institutional Repositories 38 39 Manuscripts India has the largest collection of manuscripts in the world (5 million Approximately). India is the repository of an astounding wealth of ancient knowledge belonging to different periods of history, going back to thousands of years. Most of this knowledge belonging to different areas of intellectual activity such as religion, philosophy, science, arts and literature is preserved in the form of manuscripts. Composed in different Indian languages and scripts, they are preserved in materials such as birch bark, palm leaf, cloth, wood, stone and paper. National Manuscript Mission was launched five-year programme in Feb., 2003 by the Ministry of Human Resource Development, Govt. of India to get all the manuscripts and conserve them. http://namami.nic.in/ Archives of Indian Labour V.V.

Locate both physical and digitized versions of scholarly articles and books. Optimize searches, simultaneously search the Internet, commercial databases, and library collections. Save search results and conduct additional processing to narrow or qualify results. From search results, click through to access the digitized content or locate additional items of interest. All of these capabilities are available from the desktop or other Web-enabled device such as a personal digital assistant or cellular telephone. Conclusion Digital Libraries are redefining the role of libraries in society & the role of librarians & information specialists National level mechanism is essential to promote and coordinate open access and public domain digital library systems Improve awareness of open access Regular training – tools, processes, standards Support setting up of working models, services National Resource Centre for open access publishing International agencies like UNESCO, ICSU, ICSTI, CODATA need to actively promote and support developing country initiatives References Digitization Of Library Forum Survey 2010.
