A hypermedia system, based on the text and graphics of an existing manual, was developed to provide information on forest seedling nursery disease and insect problems and their management. An expert system was included to guide the choice of links to follow in order to access the most suitable information for diagnosing unknown problems. The expert system used a filtering process in relation to a threshold value to drop or retain possible choices of links to follow. Successive application of the filtering process is analogous to a complex database query.
