Hypertexts bridge taxonomies.
We use hypertext to connect things without necessarily placing them together.
Hypertexts are fundamentally different from hierarchical, heterarchical, and sequential taxonomies, because they don't change where things are located, just how they're found.
We use hyperlinks to allow users to jump between taxonomies instead of duplicating or moving content. For example, we might hyperlink the bolded words throughout this book. If a user clicks on one of them, we could take them to a definition in the lexicon. We're moving the user to the content instead of repeating it.
A signpost directing you to a store around the corner is also hypertextual, because it sends you to a specific location without changing the location of the store.
Similarly, websites use hypertext to link to content without needing to repeat it.
