Primary Sources are often used as the foundation of research for secondary sources. They include photographs, oral histories, raw data, interviews, letters, journals, and other unpublished works. They could also include the study of original artwork and music as well as natural history materials like geological samples and the accompanying data from the Badlands. Tribal codes and laws (as are county, state, and federal) are also primary sources.
Secondary Sources are books, articles, and films, both journalistic and academic, that authors/creators used primary sources to interpret/create the content. Examples include articles about art/music, textbooks, biographies, and film or political commentaries.
Tertiary Sources are indexes, directories, and bibliographies. Wikipedia is considered a tertiary source because while most of it has excellent sources in the reference section, it can still be edited and changed by anyone and it can be hard to verify the information if there are no references cited. It is best to check those references yourself and cite them directly.
