The document discusses the importance of software in modern libraries, particularly for creating digital libraries. It details four types of digital library software: DSpace, Greenstone, Eprints, and Fedora, including their features, capabilities, and target usage. A comparative analysis of these software packages highlights their strengths and weaknesses, suggesting that DSpace and Greenstone are well-suited for digital library creation.
Digital library software
- 1. Presented by: Surya Pratap Singh Department of Library & Information Science, AMU, Aligarh
- 2. INTRODUCTION Software's now-a-days became the life line of modern day organizations. Libraries also need software if they want to create a parallel digital library with features which we may not find in a traditional library.
- 3. DIGITAL LIBRARY SOFTWARE Digital libraries are defined in many ways. It is an organised searchable collection in digital format. There are quite a few digital library software packages available in the market one has to select the right kind of packages, depending on their specific needs. There are a few library automation software packages which have a separate digital library module.
- 4. Cont.… So, now we will be discussing four types of digital library software: Dspace Greenstone Eprints Freoda
- 5. DSPACE DSPACE is a digital repository system, designed to capture, store, index, preserve and redistribute the intellectual output of an organization in digital formats. Developed jointly by Massachusetts Institute of Technology (MIT) Libraries and Hewlett-Packard (HP). DSPACE, originally released in November 2002, is built in Java. DSPACE being an as open source software can be customized and extended. It runs on any UNIX-type OS, such as Linux, HP/UX, or Solaris. DSPACE accepts all manner of digital formats. Some examples of items that DSpace can accommodate are: Documents, such as articles, preprints, working papers, technical reports, conference papers, Books ,Theses, Dissertations, Data sets, Computer programs Visualizations, simulations, and other models Multimedia publications, Administrative records, Published books, Overlay journals, Bibliographic datasets, Images Audio files, Video files Reformatted, digital library collections, Learning objects Web pages.
- 7. GREENSTONE Greenstone is developed by the New Zealand Digital Library Project in the Computer Science Department at the University of Waikato, and distributed in cooperation with UNESCO and the Human Info NGO. Greenstone is a suite of multilingual software for building and distributing digital library collections, including organizing information and publishing it on the internet or on a CD-ROM. Its aim is to empower users, particularly in universities, libraries and other public service institutions to build large distributed digital library collections. Greenstone was originally released in 2000. Greenstone is mainly programmed in C++ and Perl and runs on all versions of Windows, and Unix/Linux, and Mac OS-X. It is fully documented in English, French, Spanish and Russian.
- 9. EPRINTS EPrints was developed at the University of Southampton, U.K. with the first version of the software publicly released in late 2000. The objective behind the creation of EPrints was to facilitate open access to research and scholarly literature . In other words, EPrint is a digital archive of the research output created by the scientists, faculty, research staff and students of an institution and accessible over the internet to end-users both within and outside the institution. As a facility, it consists of hardware, software and procedures to capture, organize, archive, disseminate and manage digital research resources of an institution. It also serves as an archive for other electronic documents such as images and audio. Eprints is programmed on Perl and runs on any number of Linux distributions, and other UNIX-like systems including OS-X. It can also run on Windows Vista and XP.
- 11. FEDORA The Fedora project was funded by the Andrew W. Mellon Foundation to build a digital object repository management system based on the research paper, “Flexible Extensible Digital Object and Repository Architecture (FEDORA)”. Fedora is developed jointly by the University of Virginia and Cornell University. Fedora supports digital asset management, institutional repositories, digital archives, content management systems, scholarly publishing enterprises and digital libraries. The system, designed to be a foundation upon which interoperable web- based digital libraries, institutional repositories and other information management systems can be built, demonstrates how distributed digital library architecture can be deployed using web-based technologies such as XML and Web Services. Fedora was released in May 2003. Fedora, designed in Java, can be configured using other databases such as Oracle. It runs on Linux operating system.

- 21. CONCLUSION Digital library can be created by using open source software available free of cost. Free and open source software are a useful and significant tool for the developing countries. Comparative study has been shown between the software, which should help users to understand the differences and make an informed choice between the software's. Comparison concludes that- Greenstone and Dspace are appropriate software's for creating digital libraries. Dspace used for creating large and complicated digital libraries. Greenstone known for its simplicity.
