Abstract. As current digital libraries are becoming more complex, the facilities provided by them will increase and the difficulty of learning associated with the complexity of using these facilities will also increase. In order to produce usable and useful interactive systems, designers need to ensure that good design features are incorporated into the systems, taking into consideration end-users' needs and cultural backgrounds. We carried out a study to investigate useful design features digital libraries should have. The study provides insights on the usability impact of digital libraries for task completion and end-users' perceived impressions on the effectiveness of the digital libraries. The results also suggest that there is little provision on the interface to cater to end-users' browsing and inter-cultural needs. Hence, this paper also discusses design guidelines for the design of user-centred digital libraries.
The majority of current digital libraries (DLs) are not designed for children. For DLs to be popular with children, they need to be fun, easy-to-use and empower them, whether as readers or authors. This paper describes a new children's DL emphasizing its design and evaluation, working with the children (11-14 year olds) as design partners and testers. A truly participatory process was used, and observational study was used as a means of refinement to the initial design of the DL prototype. In contrast with current DLs, the children's DL provides both a static as well as a dynamic environment to encourage active engagement of children in using it. Design, implementation and security issues are also raised.
A preliminary study was conducted to help understand the purpose of digital libraries (DLs) and to investigate whether meaningful results could be obtained from small user studies of digital libraries. Results stress the importance of mental models, and of "traditional" library support.
