E-education in the UK
The paper outlines the results of a survey, by the EBONI project, of lecturers’ use of and attitudes to electronic teaching and learning material, providing a snapshot of the current situation in UK higher education. Differences in the extent and type of e-content usage between academic disciplines, and lecturers’ intentions for the future, are discussed. Based on an analysis of their hopes and concerns, recommendations are made for increasing the development, usage and effectiveness of electronic content.

E-Book Technology and Its Potential Applications in Distance Education
The potential for distance learning students to use e-books is explored. E-books are gaining wider interest since the introduction of portable electronic reading devices and software-based readers that provide users with more realistic book reading experiences. The paper discusses where to acquire e-book technology, and how to create e-books. It also reports an evaluation to test the usability of different types of e-book compiler software. By using one of the compilers, the use of e-books to improve the interaction between educators and distance learning students in terms of access to teaching and learning materials and submission of assignments is also demonstrated.

Use and Abuse of Reusable Learning Objects
The term Learning Object, first popularized by Wayne Hodgins in 1994 when he named the CedMA working group "Learning Architectures, APIs and Learning Objects", has become the Holy Grail of content creation and aggregation in the computer-mediated learning field. The terms Learning Objects (LOs) and Reusable Learning Objects are frequently employed in uncritical ways, thereby reducing them to mere slogans. The serious lack of conceptual clarity and reflection is evident in the multitude of definitions and uses of LOs. The objectives of this paper are to assess current definitions of the term Learning Object, to articulate the foundational principles for developing a concept of LOs, and to provide a methodology and broad set of guidelines for creating LOs.

Personalising Electronic Books
The paper addresses how hyperdocuments, accessible via electronic books (e-books) which are read using the World Wide Web, can be endowed with features that personalise the interaction process that takes place between the reader and the e-book. A novel, abstract approach to modelling the personalisation of hyperdocuments is introduced. This approach aims to make available features that allow readers to interact with these documents in a manner much closer to that with paper-based documents. The research is based on a formal characterisation of personalisable hyperlink-based interaction. This characterisation is unique in formally modelling a rich set of user-initiated personalisation actions that allow users to come closer to satisfying their specific, often dynamic, information retrieval goals.

E-nhance Lectures
Ever more lecturers find themselves forced to Web-enhance their courses out of economic pressure or prestige. Universities trapped between rising student numbers and decreasing budgets are turning to e-learning as the one-stop solution, with little concern for student or teacher needs. An e-(nhanced) learning environment can only be successful if it fulfils students' and lecturers' needs alike. The student needs to be supported in various stages of learning, whereas the lecturer cannot afford to spend more time on generating lecture support materials. Investigation of lecturers' and students' requirements resulted in the concept and design of e-ULE (e-Usable Learning Environment), a university-level teaching and learning environment with a strong focus on usability. To ensure learning materials are helpful for students in any learning situation, from gaining an overview to providing reference, an equally usable authoring tool is required: e-ULE's authoring system is geared towards a typical lecturer, without requiring an undue amount of IT or pedagogical skills, but offers support for academic workflow by supporting tasks like literature research and integration, and collaborative editing in large groups (e.g. with students). Following a usability engineering approach, all features of the e-ULE learning environment are derived from user requirements and usability tests. The main parts of the environment are currently at "proof of concept" stage. The system is open source and relies on several prominent open source projects.

Towards Modular Access to Electronic Handbooks
The paper reports an ongoing project aimed at providing an exemplary architecture for an electronic dissemination environment for scientific handbooks. It focuses on a way of facilitating navigation through and access to electronic handbooks by using a WordNet-like concept hierarchy consisting of synsets (sets of synonyms) that are connected to each other and to external sources by semantic relations for navigational purposes.
