The ECO Browser is the prototype of a Prolog browser for a large knowledge base of loosely structured observational information. Its purpose is to provide a way for users quickly to access the information they require without necessarily having predetermined ideas about the things that are of interest to them. The browsing mechanism is based on simple principles. We adopt an approach which relies on a gradual narrowing of the area of interest, until the desired information is found. Recent small scale tests suggest that this method is natural and easy to use, although a short introductory session is often required. Several extensions to the current system are suggested, including the incorporation of intelligent guidancemethods
