A series of query techniques and participatory design workshops were employed with the goal of actively involving users in identifying the key characteristics and applications of IV for DLs. The methodology employed, key findings and overall conclusions are presented and discussed.

A poorly designed digital library (DL) is certainly a barrier to users; therefore the need exists for a specific usability and accessibility framework for the design and evaluation of DL's, which if adopted can help ensure enhanced usability of a service. The framework consists of three stages-query techniques, user testing and expert evaluations, and embodies the need for assessment after each stage. The framework also defines the techniques and ...

The methodology employed, key findings and overall conclusions are presented and discussed.

The usability and accessibility of fifty selected UK egovernment websites were measured using two automatic evaluation tools: Bobby and LIFT. Based on these automatic evaluation results, ten selected websites were further evaluated with expert evaluation methods: heuristics evaluation and cognitive walkthrough. Assistive technology was also used in the evaluation to assess the accessibility issues. The results show a relatively high compliance with the Web Content Accessibility Guidelines and a relatively low usability rating for most UK e-government websites.

The results obtained from a case study, where four Joint Information Systems Committee (JISC) services were evaluated, are also presented. The applicability of the framework to similar evaluations is identified.
