Lateral reading is basically searching for information about a source while you are reading it; you are checking for currency, relevancy, authority, accuracy, and purpose (CRAAP method) by reading what other sites say about your source. This is different from vertical reading where you apply the CRAAP method using only the information the site itself provides you.
The concept of lateral reading originated from research by the Stanford History Education Group (SHEG) under Sam Wineburg, the founder and executive director, and is used by professional fact checkers.
