Abstract

The success of the World Wide Web Shows that we can access, search, and retrieve information from globally distributed databases. lf a database, such as a library catalog, has some sort of Web-based front end, we can type its URL into a Web browser and use its HTML-based forms to search for items in that database. Depending an how well the query conforms to the database content, how the search engine interprets the query, and how the server formats the results into HTML, we might actually find something usable. While the first two issues depend an ourselves and the server, an the Web the latter falls to the mercy of HTML, which we all know as a great destroyer of information because it codes for display but not for content description. When looking at an HTML-formatted display, we must depend an our own interpretation to recognize such entities as author names, titles, and subject identifiers. The Web browser can do nothing but display the information. lf we want some other view of the result, such as sorting the records by date (provided it offers such an option to begin with), the server must do it. This makes poor use of the computing power we have at the desktop (or even laptop), which, unless it involves retrieving more records, could easily do the result Set manipulation that we currently send back to the server. Despite having personal computers wich immense computational power, as far as information retrieval goes, we still essentially use them as dumb terminals.
