In Chapter 3, Finding Wikipedia's Content, we described many ways to browse Wikipedia. For instance, readers can explore Wikipedia via the links between pages or through categories of related articles. If an area of Wikipedia has been worked on for long enough, these browsing journeys go smoothly. But Wikipedia's content does not start out perfectly linked or classified, and new articles need to be integrated with existing content. Articles need care and attention to become fully usable in the context of the rest of the site.

This chapter turns to web-building techniques on Wikipedia. You can add to, alter, and mend Wikipedia as a piece of hypertext. We'll cover six concepts for building navigational structures, linking articles, and maintaining article organization. These concepts have been mentioned in previous chapters, but here we'll present them as editorial tools.

First, we'll cover redirecting one page title to another and building disambiguation pages, both of which help readers navigate, avoid duplication, and search the site more productively. We'll then focus on how articles are combined, split apart, or moved to better titles in order to comply with style guidelines and to make them more useful for the reader. In the next section, we'll discuss categories and categorization, which help readers navigate similar topics and editors maintain sets of pages. Finally, we'll review community processes for resolving problems that arise related to these topics.
