This research examines how electronic documents (e-documents) such as electronic journals (e-journals) could be enhanced in the electronic environment to make them more valuable to end-users. In particular, it investigates how a wide range of information searching, analysis and communicating tasks involved in interacting with e-documents could be supported within a single user interface (UI) environment, using e-journals as an example of e-documents. The research tasks completed in the study include the elicitation of user needs and wants, a comprehensive review of latest research developments in electronic publishing and e-documents, derivation of a new set of information and interaction properties that are necessary for a new digital environment to support enhanced access and value-adding to e-documents, and the design of a platform (PROPIE) to demonstrate the use of various features and functionality to support creative and effective e-document use. Providing a suite of novel features and interactive tools that could be flexibly combined, PROPIE allowed users to apply multiple novel ways to intuitively query and navigate information in edocuments. The querying and browsing processes in PROPIE were supported by various interactive and visualization techniques. A set of interface mock-ups was developed to demonstrate the potential of PROPIE in supporting the design of a new-generation of e-journals. Following that, a series of empirical evaluations of various aspects of the environment was conducted using up to a sample of 83 graduate students in three separate tiers to obtain representative users' feedback with regard to interacting with e-journals. This paper reports the major research findings of these evaluations. In particular, it describes the types of features, tools and interaction identified as desirable and required in future e-journals systems. The conclusions were that top-ranked features of e-journals were those not available in print journals and included those of querying, navigation and visualization that contributed to enhanced access, advanced interaction and value-adding contents. 2
