Autobiographies, diaries and memoirs are considered primary sources because they are first hand accounts of events. Search for these in the Library Catalog by searching for a person's name as author: e.g., Darrow, Clarence.
Or, conduct a keyword search with autobiography in the first search box and an event, historical period, or profession in the second box; for example, autobiography AND civil rights.
Search the Library Catalog for resources that contain contemporary accounts of events by using the Advanced Search form. Enter the event or historical period in the search box, and limit the publication date to the appropriate years for the event.
For example, a search for Civil War, limited to the publication years 1861-1865, returns The Causes of the American Civil War, a Letter to the London Times, along with many other items.
