A Hypertext Electronic Index based on the Structured Document Editor Grif

This paper presents an electronic index service that was developed in the Grif editor by taking advantage of the hypertext facilities available in the system. Grif is a structured document editor based on the generic structure concept that supports both hierarchical structures and non hierarchical links. The active cross-reference within the Grif index makes activation and browsing through indexing more powerful than in other systems: the index tables, helpful as a medium for supporting search by keywords in paper documents, supportbrowsing in electronic documents. These indexes are easy to use as they are displayed in the same form as indexes in a paper document.
