This paper describes our approach of using spatial hypertext as a means separated from an end representation for hypertext authoring. By taking advantage of the power of rich interpretation and constant grounding capabilities of a spatial hypertext representation, ART001, ART006, and ART014 use spatial hypertext as a means for authoring linear, hierarchical, and network structures, respectively. The role of the space of the tools includes controlling a structure and annotating a structure. The three prototyped tools have been developed to demonstrate what visual interaction design concerns need to be taken into account to integrate a spatial hypertext as a means with another structural representation as an end. The paper concludes with a discussion of what it means to separate representations as a means from those as an end in hypertext authoring.
