Here’s three websites about The Battle of Antietam need to analyze. Analysis based on: Currency or Timeliness – How recent is the information? (are sources listed from within the last 10 years?)
Authority – Does the author or organization cite their sources, are they peer-reviewed?
Audience – Is the article written to the general public or more towards scholars/higher ed researchers?
Relevance – Does the information relate to the topic?
Perspective – Is the writer objective or clearly biased? Is the website pushing a particular viewpoint or agenda?
