Choose historically appropriate keywords. For example, use "Great War" instead of "World War I" to locate documents discussing the war during and just after it occurred. You may also consider different terms that might have been used to describe the same event from opposing sides or perspectives. Searching for the names of particular people or places may also be effective.
