Secondary sources exist as works that examine, assess, or interpret a historical event, era, or sensation, generally operating primary sources to do so. Secondary sources often offer an assessment or a critique. Secondary sources can contain books, journal articles, speeches, reviews, research reports, and more. In scholarship, a secondary source exists as a document or recording that relates or discusses information originally submitted elsewhere.
Scholars writing about recorded events, people, objects, or ideas create secondary sources because they help describe new or various positions and ideas about primary sources. These secondary sources are generally academic books, including textbooks, commentaries, encyclopedias, and anthologies.
Reviewing secondary source material can be of importance in enhancing your overall research paper because secondary sources promote the communication of what exists known about a topic.
