Overall Performance

The popularity of the World Wide Web has led to an exponential increase of the traffic generated by its users for over a decade. Such a growth, over such a long period of time, would have saturated both the content providers and the network links had Web caching not been efficiently deployed. Web caching can improve the overall performance of the World Wide Web in several ways, depending on the decisions made regarding the deployment of the corresponding caches. By placing caches in strategic positions, the core network traffic can be reduced, the load of a content provider can be scaled down, and the quality of service, as the users perceive it, can be improved. In this article we present an overview of the major design and implementation challenges in Web caching, as well as their solutions.

A comparative study was made of the ways in which Australian universities are disseminating information about their courses over the World Wide Web. The study examined the quantity and quality of the information provided, the forms in which information is presented, and means of access to the information. The results of the survey indicated that while the majority of universities are now publishing at least some information over the World Wide Web, both the quantity and quality of information is variable. Implications for further development of institutional course information databases are discussed.

AbstractIntroduction:This study aimed to assess the quality of information available on the World Wide Web for patients undergoing thyroidectomy.Methods:The first 50 web-links generated by internet searches using the five most popular search engines and the key word ‘thyroidectomy’ were evaluated using the Lida website validation instrument (assessing accessibility, usability and reliability) and the Flesch Reading Ease Score.Results:We evaluated 103 of a possible 250 websites. Mean scores (ranges) were: Lida accessibility, 48/63 (27–59); Lida usability, 36/54 (21–50); Lida reliability, 21/51 (4–38); and Flesch Reading Ease, 43.9 (2.6–77.6).Conclusion:The quality of internet health information regarding thyroidectomy is variable. High ranking and popularity are not good indicators of website quality. Overall, none of the websites assessed achieved high Lida scores. In order to prevent the dissemination of inaccurate or commercially motivated information, we recommend independent labelling of medical information available on the World Wide Web.

New Procedures

The World Wide Web is particularly suited as a communication medium for the deaf community. A wealth of deaf-related online information is available on subject specific, special purpose, and comprehensive sites that provide important resources for deaf people, their families, and involved professionals. Librarians now face the challenge of devising new procedures for teaching users how to search for inform ation and more importantly, how to evaluate the quality of what is retrieved.
