History, United States

The goal of this guide is to highlight some key resources for researchers interested in the history of the United States of America from prehistoric times to today.

Primary and Secondary Sources

Primary Sources

For certain assignments you might be asked to use primary sources. Primary sources are works created at the time of an event, or by a person who directly experienced an event.

It is the content that matters and an on-line source can still be a primary source. For example, an online copy of a newspaper from May 8, 1945, is still a primary source even though the original article has been digitized.

Primary sources can include:

  • Interviews, diaries, letters, journals, speeches, autobiographies, and witness statements
  • Original hand-written manuscripts
  • Government documents and public records
  • Art, photographs, films, maps, fiction, and music
  • Newspaper and magazine clippings
  • Artifacts, buildings, furniture, and clothing

Secondary Sources

Secondary sources are works that are written after the original event or experience; they provide criticism or interpretation of the event or experience.

Some examples of secondary sources are:

  • Textbooks
  • Biographies
  • Historical films, music, and art
  • Articles about people and events from the past
