Information timeline

When searching for information, it is always wise to keep in mind the information timeline. It is very easy to find plenty of books and encyclopedia articles on ancient Egypt, the Great Depression, and World War II. Finding information and scholarly articles about the Islamic State insurgency and the most recent ebola outbreak is going to be somewhat more difficult.
