There are many resources available to help us understand Adlai's life, words, and work. These include primary sources, secondary sources, and interpretations.
Primary Sources* are like clues that help us discover what things were like in the past, and how and why things have changed over time. Examples include letters, recorded speeches, photographs, newsreels, and diaries.
Secondary Sources* are accounts written after the event, based on primary sources or other secondary sources. Examples include history books, textbooks and biographies.
When historians read and examine both primary and secondary sources, they apply their knowledge of history to analyze and interpret these sources. Historians consider what else was going on at the time an event took place. What were the predominant influences? Has something similar ever happened before? History interpretations can be found in many places, such as museum exhibits, movies, plays, websites, books, magazines, and newspapers. A search for Adlai Stevenson or another history keyword in Today's News demonstrates how news articles and editorials ("opinion" articles) are resources that come into existence on a daily basis.
