This document describes techniques and apparatuses enabling affinity-based page navigation. These techniques and apparatuses enable page navigation, such as page flipping, page searches, and other navigation based on affinities associated with various pages. These affinities can include a reference to a page, such as a link or quotation in a social networking service, an encyclopedia, a webpage, an article, a newspaper, or a blog. These affinities can also or instead include usage, such as how many users have read, highlighted, dog-eared, or bookmarked a page.
