This is a pressbook designed to teach web literacy for students who engage in fact-checking. From the book: "This guide will show you how to use date filters to find the source of viral content, how to assess the reputation of a scientific journal in less than five seconds, and how to see if a tweet is really from the famous person you think it is or from an impostor. It’ll show you how to find pages that have been deleted, figure out who paid for the website you’re looking at, and whether the weather portrayed in that viral video actual matches the weather in that location on that day. It’ll show you how to check a Wikipedia page for recent vandalism and how to search the text of almost any printed book to verify a quote. It’ll teach you to parse URLs and scan search result blurbs so that you are more likely to get to the right result on the first click. And it’ll show you how to avoid baking confirmation bias into your search terms."
