That on the left, the overview for Elizabeth Gaskell's North ond South in The Victorion Web, represents the latestversion ofthe lntermedia-style overviews, which emphasize that readers can approach a subject from multiple points ofview.The A' S' Byatt overview, in contrast, Presents a similarly nonhierarchical approach to organizing information, by arranging itslinked headings in a series of horizontal rows. This approach to creating overviews with HTML (text) documents has severaladvantages over image maps: (1) this text-based overview loads (opens) fasterthan server-based image maps; (2) since InternetExplorer, Safari, Netscape, and other web browsers retain images in a cache, building different overviews with the same elementscreates documents that load very quickly; (3) such overviews are easily modified by adding or subtracting individual icon-and-linkcombinations; (4) these overviews have the advantage of employing the same files for both overviews and footer icons. thusreducing storage space and access time.these kinds of overviews will work with old-fashioned browsers that do norhave graphics capacities-an important consideration when porrions ofone's intended audience may not have the kind of computer access or equipmentneeded to handle large images. Moreover, one may create standardtemplates for all the overviews in a particular web, thus producing a kind ofvisual consistency, and yet one can easily modify appropriate elements. In theGaskell overview, for instance, "works" replaces "other works," and in thosefor other texts other icons appear, including those for themes, bibliography,related'World Wide Web materials, and so on.
