What makes a useful web site? You can evaluate a web page using much the same criteria as you would use for a magazine or a book. The quality of the text and authority of the author and publisher are crucial, but in the case of web pages the presentation of a page and the structure of a site become crucial. The Widener University Library provides a tutorial on Evaluating Web Resources. It provides criteria for five distinct types of pages, additional material for use in training, and samples from the Internet. A brief summary of points to look for, look at Thinking critically about World Wide Web resources Jami McKenzie suggests some essential criteria - reliability, accuracy, authority, currency, fairness, adequacy, efficiency and organisation. EdNA has a strict set of guidelines for accepting web pages for inclusion in its approved sites list. The guidelines ensure the quality of sites from the core EdNA list. Metadata is becoming an increasingly important issue on the Internet. Metadata is data about data, and in the case of the net, is information about the contents of a web page or other resource. Such information can be included on a page by the author, but is not normally displayed when viewing the page in a browser. The data is available for use by search tools to catalogue the web page. Standardising metadata is by far the most effective way of improving a users ability to locate information. EdNA has an agreed standard on Metadata which is based on the Dublin Core standard. |
