Historians use different kinds of sources to study the past. Sources are books, documents, pictures, or other materials that provide evidence about the past. Primary sources are usually firsthand accounts and are usually created at the time that an event takes place. Secondary sources are usually secondhand accounts, are usually created later in time, and are based on a variety of primary sources.

A program was given to people who attended a baseball game between the Indianapolis Clowns and the Kansas City Monarchs in the 1950s. These teams played in an African American baseball league.
To learn about the past, historians look at many different sources. Sources are books, documents, pictures, or other materials that provide evidence about the past.
The sources that historians use fall into two categories: primary sources and secondary sources. The category for a source can change depending on what the historian is trying to learn, who created the source, and when it was created.
The table below shows some common characteristics of primary and secondary sources.
 | Primary source | Secondary sources
Description | firsthand accounts of a historical event that the historian is studying | secondhand accounts of a historical event that the historian is studying; sources that interpret or analyze many primary sources
Author | usually created or used by a person who participated in the event | usually created by someone who did not participate in the event
Date | usually created at or around the time of the event | usually created after the event
Common examples | speeches; diaries; letters; photographs; artifacts such as household objects; exact copies of sources or artifacts; | textbooks; history books; documentary (non-fiction) films; articles by historians; museum exhibits
Some sources are neither primary nor secondary sources because they do not provide historical information about the topic being studied. For example, a historian would not use a historical novel to learn about an event. Other sources may not relate to a historian's goal.
