Primary sources are original materials created at the time or soon after an event occurred. Materials created at a later time by someone who was involved in or witnessed the event are also primary sources. Materials such as diaries, photographs and letters.
Secondary sources describe, analyze, interpret or summarize events or primary sources. Such sources are often created significantly later than the time the event occurred, or the primary source was created. Sources such as enyclopedias, biographies and textbooks.
