- Abstract
- Digital libraries have become commodity in the current world of Internet. More and more information is produced, and more and more non-digital information is being rendered available. The new, more user friendly, community-oriented technologies used throughout the Internet are raising the bar of expectations. Digital libraries cannot stand still with their technologies; if not for the sake of handling rapidly growing amount and diversity of information, they must provide for better user experience matching and overgrowing standards set by the industry. The next generation of digital libraries combine technological solutions, such as P2P, SOA, or Grid, with recent research on semantics and social networks. These solutions are put into practice to answer a variety of requirements imposed on digital libraries.

- Abstract
- Purpose - System usability and system usefulness are interdependent properties of system interaction, which in combination, determine system satisfaction and usage. Often approached separately, or in the case of digital libraries, often focused upon usability, there is emerging consensus among the research community for their unified treatment and research attention. However, a key challenge is to identify, both respectively and relatively, what to measure and how, compounded by concerns regarding common understanding of usability measures, and associated calls for more valid and complete measures within integrated and comprehensive models. The purpose of this paper is to address this challenge. Design/methodology/approach - Identified key usability and usefulness attributes and associated measures, compiled an integrated measurement framework, identified a suitable methodological approach for application of the framework, and conducted a pilot study on an interactive search system developed by a Health Service as part of their e-library service. Findings - Effectiveness, efficiency, aesthetic appearance, terminology, navigation, and learnability are key attributes of system usability; and relevance, reliability, and currency key attributes of system usefulness. There are shared aspects to several of these attributes, but each is also sufficiently unique to preserve its respective validity. They can be combined as part of a multi-method approach to system evaluation. Research limitations/implications - Pilot study has demonstrated that usability and usefulness can be readily combined, and that questionnaire and observation are valid multi-method approaches, but further research is called for under a variety of conditions, with further combinations of methods, and larger samples. Originality/value - This paper provides an integrated measurement framework, derived from the goal, question, metric paradigm, which provides a relatively comprehensive and representative set of system usability and system usefulness attributes and associated measures, which could be adapted and further refined on a case-by-case basis.

- Abstract
- This chapter describes not so much what digital libraries are but what digital libraries with semantic support could and should be. It discusses the nature of Knowledge Organization Systems (KOS) and how KOS can support digital library users. It projects a vision for designers to make and for users to demand better digital libraries. What is a digital library? The term \Digital Library" (DL) is used to refer to a range of systems, from digital object and metadata repositories, reference-linking systems, archives, and content management systems to complex systems that integrate advanced digital library services and support for research and practice communities. A DL may offer many technology-enabled functions and services that support users, both as information producers and as information users. Many of these functions appear in information systems that would not normally be considered digital libraries, making boundaries even more blurry. Instead of pursuing the hopeless quest of coming up with the definition of digital library, we present a framework that allows a clear and somewhat standardized description of any information system so that users can select the system(s) that best meet their requirements. Section 2 gives a broad outline for more detail see the DELOS DL Reference Model.
