Greenstone and Dspace are widely used software systems for digital libraries. The Present article discusses about the digital library. The rapid changes in digital library developments are pervasive. The Open Source based software development model provides industry, government, and academia with significant opportunities to leverage. This paper deals with the concept of Open Source Software. It gives advantages of digital library. It explains the Role of OSS in learning and teaching. It Provides that how to choose an Open Source library. It will also provide popular open source software for digital library in India.

3. What is Digital Library? Definitions A digital library contains digital representations of the objects found in it - most understanding of the "DL" probably also assumes that it will be accessible via the Internet, though not necessarily to everyone. But the idea of digitization is perhaps the only characteristic of a digital library on which there is universal agreement. Digital Library a collection of material organized to provide physical, bibliographical, and intellectual access to a target group with a staff that is trained to provide services and programs related to the information needs of the target group" We can say that: “An informal definition of a digital library is a managed collection of information, with associated services, where the information is stored in digital formats and accessible over a network”

6. Multiple accesses

7. Information retrieval

9. Role of Open Source Software (OSS) in Learning and Teaching The Absence of license fees: Most of the times institutes pay a plenty of amount of software’s companies to use their products but open source are license free. Flexibility: OSS are flexible they are easy to customized and free modules and other features are also imported through the community. Service Community: Forums are the networks of people who share their experiences and also come up with features which are communicated among forums.

10. Why and how to choose Open Source? Open source means the software code is available to users and developers, with few restrictions on usage, modification or distribution. Open Source Software is widely deployed by corporations and governments for robust applications in business, education and science. Extensibility Low cost Security

11. Popular Open Source Software for Digital Library in India DSpace Why DSpace? • Dspace is an open source technology platform which can be customized or extend its capabilities. • Dspace is a service model for open access and/or digital archiving for perpetual access. • Dspace is a platform to build an Institutional Repository* and the collections are searchable and retrievable by the Web. • To make available institution-based scholarly material in digital formats. The collections will be open and interoperable.

12. Popular Open Source Software for Digital Library in India FEDORA The fedora is based on the flexible extensible Digital object and Repository Architecture (FEDORA). It can be used to develop institutional repositories and other interoperable web-based digital libraries and the system implements the fedora architecture, adding utilities that facilitate repository management. It has been developed by the university of Virginia and Cornell University. Characteristics of Fedora Preservation Metadata Access System Features

13. Popular Open Source Software for Digital Library in India EPRINTEPrints Open Source Software is a platform for building repositories of research literature, scientific data, student theses, project reports, multimedia artefacts, teaching materials, scholarly collections, digitised records, exhibitions and performances. EPrints is free software developed by the University of Southampton, England. EPrints is the most flexible platform for building high quality, high value repositories, recognised as the easiest and fastest way to set up repositories.

14. Popular Open Source Software for Digital Library in India KOHA 2.2 Kohaversion 2.2 is a free/libreopen sourceintegrated library system (ILS) for automating a lending library. It has all of the basic features needed to run a library, handling: an online public access catalogue (OPAC) of the library's holdings; a database of library users; issuing books to borrowers and returning books to the collection; borrower requests for library items; orders from vendors; book budgets; transfers between library branches; management of subscriptions to periodical publications; and most other functions associated with operating a lending library.

15. Popular Open Source Software for Digital Library in India GREENSTONE Greenstone is a suite of software for building and distributing digital library collections. It provides a new way of organizing information and publishing it on the Internet or on CD-ROM. Greenstone is produced by the New Zealand Digital Library Project at the University of Waikato, and developed and distributed in cooperation with UNESCO and the Human Info NGO. It is open-source, multilingual software, issued under the terms of the GNU General Public License. WHY LIBRARIES NEEDS OPEN SOURCE Severe budget cuts. Increased demand for services. Lack of adequate staffing

16. Conclusion Free Software Foundation and the Open Source Initiative work to help each other, they are not the same thing. The Free Software Foundation uses a specific license and provides software under that license. The Open Source Initiative seeks support for all open source licenses, including the one from the Free Software Foundation. These initiatives have much potential for libraries and information centers and there are numbers projects, including Koha, Greenstone, Dspace, Fedora etc.Collections may be built and served locally from the user’s own web server, or remotely on a shared digital library host. Open Source essentially empowers less privileged communities though it does not follow that it is meant only for them. There is no denying the fact that OSS enables bridging the digital divide in more ways than one. Libraries in the developing countries are able to support electronic access, digital libraries.
