Hypertext creates a multdimensional, borderless, information space. With the addition of multimedia, the information space becomes multisensory.
The concept of information space is an important one, I define an information space as being a subset of cyberspace as a whole, rather as Vancouver, B.C. is a subset of Canada, which in turn is a subset of the planet. Thus information spaces can be a part of a larger information spaces until we reach cyberspace as whole. Prior to the Internet and the WEB, information spaces were isolated Islands, now they are part of a integrated whole. Like geographic space, an information space has dimensions, places, and one can move through it. The dimensions of the overall information space known as the WEB is the extent of the Internet, at a more local level the dimensions of an information space is the extent of the site, the city limits so to speak. The places are the sites and nodes within the sites. Just as one can throw up a new subdivision, one can throw up a new site. Traveling though this space can be either by established links, or one can bushwhack one's own trail. Viewing the WEB though the metaphor of geographic space aids one both in viewing a given site or document in a wider context, and in grasping the nature of the WEB as a whole.
