Storyspace supports a graphical display of the structure of the hyperdocument, including composite nodes and links going in and out of composites. This ability to manipulate the structure of a hyperdocument graphically makes Storyspace suitable for interactive and collaborative writing. Collaboration was initially somewhat hindered by the (only) hardware and software platform: the Apple Macintosh. Nowadays Storyspace is also available for Windows on the IBM-PC.
An increasing number of hyperdocuments for Storyspace is becoming (commercially) available, ranging from children's fiction to historical works and encyclopedia.
