Secondary Sources. The most common type of source you are likely to encounter is a secondary source. A secondary source is any source about an event, period, or issue in history that was produced after that event, period or issue has passed. Aside from a textbook, the most commonly assigned secondary source is a scholarly monograph - a volume on a specific subject in the past, written by an expert. Also common are articles in scholarly journals, which are similar to monographs, but on a smaller, more focused scale.
The authors of secondary sources develop their interpretations and narratives of events based on primary sources, that is, documents and other evidence created by participants or eyewitnesses. Frequently, they also take advantage of the work of other historians by using other secondary sources. For example, the author of the history textbook which you use in school probably did not use too many primary sources. Instead, textbook authors usually rely on secondary sources written by other historians.
