- 3. INTRODUCTION TRADITIONAL LIBRARY DIGITALLIBRARY • Librarians aim is to enrich and organize the library collections so as to enable users to locate individual items easily. • Users search the physical catalogue or the online catalogue(OPAC) and locate on shelves. • Librarians aim is to guide its users to quickly identify the most reliable and suitable digital items. • Users directly search the digital library and locate the items from a single DL or from DLs located at different physical locations.
- 5. A functionof the operating system that allows individuals to access and command the computer. User Interface(UI), the junction between a user and a computer program. An interface is a set of commands or menus through which a user communicates with a program. Visual part of computer application or operating system through which a user interacts with a computer or a software. It determines how commands are given to the computer or the program and how information is displayed on the screen. WHAT IS USER INTERFACE
- 6. NEED OF EFFECTIVEUI A digital library is a large-scale, organized collection of complex and dynamic multimedia information and knowledge, and tools and methods to enable search manipulation and presentation of this information and knowledge via Internet. Since the digital libraries are running on the Internet and the users are from different psychological, educational and social backgrounds, the usage of digital libraries is varying from user to user which entail the need of best user interface (UI).
- 7. DESIGN OF UI It is the job of a user interface to make a program easy to use. A good user interface should: • Be attractive and pleasing to the eye. • Be easy to use. • Have all options clearly shown. • Have clear warning messages when someone makes a mistake. • Have online help and support.
- 8. UI PRINCIPLES FORDL Simple Support Familiar Informative feedback Prevent errors Multimedia support Pan and zoom support o Accuracy o Efficient searching with NLP support o Support of semantic approach and RDF technologies o Multilingual support o Platform independent o Future plug-in support
- 9. EVALUATION OF USERINTERFACE WHAT ? • Evaluation is something we actually already do, but without formally saying. • Example : buy something, then decide good enough to buy again.
- 10. WHY ? •Help us to understand the user experience with the system and, where there are difficulties, to find ways to improving it. • Does the interface meet the usability requirements ? • Why user unable to complete particular task very easily ? • Whether the UI that has been developed for novice user is acceptable to experienced users. • To find out if the user like a particular design feature.
- 11. CRITERIAS TO EVALUATE Easy to use Interactive efficiency Easy to remember behaviour The frequency and severity of the error The user satisfaction

- 14. UI OF DSPACE This software is ideal for planning, building and managing digital repositories for large institutions. DSpace has been jointly developed by Massachusetts Institute of Technology (MIT) Libraries and Hewlett-Packard (HP) and distributed under BSD Open License. This software supports community/ collection-based content and work flow submissions by different user communities (http://www.sourceforge.net). The first version of this software was started from 2002 and the latest version is DSpace v4.2. The development of DSpace has clearly defined rules and each user of the community can contribute to it with new functions (http://www.dspace.org). Therefore, DSpace is advantageous for academics and young researchers to upload and manage their works by themselves.

- 18. UI OF GSDL An international cooperative effort established in 2000 among three parties namely New Zealand Digital Library Projects at the University of Waikato, UNESCO and the Human Info NGO, Belgium has developed and distributed this product. GSDL can handle multilingual digital documents, with search and browse facility under GNU General Public License (http://www. greenstone.org). Greenstone is meant for non-specialist users to produce single and personalized collections. Its model visualizes a ‘librarian’ who is creating collections from existing resources by comprising both ‘items’ and metadata and distributing them over the Web or on removable media (Witten, 2005).
- 20. UI OF EPRINT EPrints was created in 2000 as a direct outcome of the 1999 Santa Fe meeting that launched what eventually became the OAI-PMH. Prints has been developed at the University of Southampton School of Electronics and Computer Science and released under a GPL license. EPrints is a Web and command-line application based on the LAMP architecture (but is written in Perl rather than PHP).
