Is a Documentary a Secondary Source? Explained

Are documentaries secondary sources, primary sources, or both? Dive into their classification, credibility, and the contexts that define their role in research.

Documentaries are powerful tools for research and education, but their classification as primary or secondary sources often depends on their content and purpose. While widely used for their storytelling and visual appeal, documentaries can blur the lines between direct evidence and analytical interpretation. 

In this guide, we’ll explore when a documentary qualifies as a secondary source, how it can sometimes function as a primary source, and tips for evaluating its credibility in your research.

What Is a Documentary?

A documentary is a non-fiction film designed to inform, educate, or shed light on real-life events, people, or issues. These films often blend archival footage, interviews with experts or eyewitnesses, and commentary to build a narrative or present a perspective. 

Whether exploring historical moments, social issues, or scientific advancements, documentaries aim to provide audiences with a deeper understanding of the subject matter while often reflecting the filmmaker's interpretation or message.

Types of Documentaries

Explore the variety of documentaries and how their purpose and content influence their classification as primary or secondary sources.

Historical Documentaries

Historical documentaries interpret past events, often using archival footage and expert analysis to build a narrative. While they rely heavily on primary materials like historical footage or documents, their interpretative nature generally classifies them as secondary sources.

Biographical Documentaries

Biographical documentaries focus on a person’s life story, often featuring interviews, commentary, and personal footage. These elements typically make them secondary sources, though they may contain primary source materials like personal letters, photographs, or audio recordings.

Investigative Documentaries

Investigative documentaries delve into current issues or controversies, synthesizing data from various sources and interviews. While they are mostly secondary sources due to their analysis and interpretation, they can include primary data like original interviews or exclusive footage.

Educational Documentaries

Educational documentaries are designed to teach specific concepts or topics. They summarize existing knowledge, often relying on research or expert interviews, making them secondary sources in most cases.

When Is a Documentary a Secondary Source?

Documentaries qualify as secondary sources when they analyze, interpret, or synthesize information rather than providing firsthand evidence. Let’s break down the key scenarios:

Interpretations of Events

Documentaries often provide interpretations of historical or current events, shaped by the filmmaker's perspective.
For example, a documentary about the Great Depression may analyze its causes and effects while presenting opinions from economists and historians.

Expert Commentary

The inclusion of expert commentary adds layers of analysis, further classifying documentaries as secondary sources.
For instance, interviews with sociologists in a documentary about urbanization frame the topic with academic perspectives.

Multiple Source Compilation

Documentaries frequently compile information from diverse primary sources to create a unified narrative:

• Archival footage or photographs from historical events.
  
  
  

• Recorded interviews with eyewitnesses or participants.

• Government reports, letters, or official records.
  
  This blending of sources contributes to their role as secondary interpretations.
  
  
  

Historical Contextualization

Many documentaries place historical events within broader narratives, providing context and analysis:

• A documentary on women’s suffrage might connect the movement to broader global efforts for gender equality.
  
  
  

• It may also analyze the societal shifts leading up to significant milestones, such as the passing of key legislation.

When Is a Documentary a Primary Source?

Documentaries can function as primary sources when they provide original material that directly documents events, interviews, or cultural perspectives. Let’s explore the specific scenarios:

Firsthand Event Documentation

Documentaries that directly capture events as they unfold qualify as primary sources.
Examples:

• Live footage of protests, like the Civil Rights Marches.

• War-time recordings showing battles or daily life during conflict.

Original Interviews or Footage

When documentaries feature exclusive interviews or unique footage, they serve as primary sources for the information presented.

Example: A filmmaker’s recorded interview with a historical figure offers raw, firsthand insight into their thoughts and experiences.

Evidence of Social Perspectives

Documentaries capturing societal attitudes or cultural trends during a specific era act as primary sources for studying those periods.

Example: A 1960s documentary reflecting public opinions on the Space Race can serve as a lens for understanding societal enthusiasm at the time.

Filmmaker’s Perspective

A documentary showcasing the filmmaker’s narrative choices and creative decisions is a primary source for analyzing media production and representation.

Example: A behind-the-scenes documentary reveals how filmmaking techniques shaped the portrayal of a historical event.

Evaluating Documentaries as Sources

Assessing a documentary’s reliability is essential for determining its value in research. Here’s how to evaluate key aspects:

Creator’s Intent

Understand the filmmaker’s purpose, whether to inform, persuade, or entertain. The intent shapes the documentary’s framing and its classification as primary or secondary.

Source Verification

Verify the sources cited within the documentary to ensure credibility. Cross-checking references strengthens trust in the presented information.

Identifying Bias

Evaluate for bias in narrative framing, editing choices, or the filmmaker’s perspective. Recognizing bias helps in determining the objectivity and credibility of the content.

• Narrative framing: Check if the documentary presents one-sided views or avoids opposing arguments.
  
  
  

• Selective editing: Watch for omission of facts or scenes that could present a different perspective.
  
  
  

• Filmmaker’s perspective: Analyze whether the filmmaker’s personal beliefs or affiliations influence the narrative.

Target Audience Analysis

Analyze the intended audience to understand the documentary’s purpose and tone. Audience targeting often reveals underlying motivations or slants in the content.

Using Documentaries in Research

Documentaries can be valuable tools in research when used thoughtfully. Here’s how to incorporate them effectively:

Proper Citation

Citing documentaries accurately is crucial for academic integrity. Use standardized formats like:

• APA: Include the filmmaker, release year, title, and format (e.g., "[Film].")

• MLA: List the director, title, distributor, release date, and medium.

• Chicago: Reference the documentary in notes and bibliography with details like the producer, year, and medium.
  
  
  

Supporting Research

Documentaries are excellent supplementary sources, offering:

• Illustrative examples for supporting arguments.

• Contextual background to complement primary or secondary sources.

Always cross-reference the documentary’s content with credible academic sources to verify its accuracy.

Bias and Perspective Analysis

Analyzing the bias and perspective in documentaries ensures a balanced approach in research:

• Identify the filmmaker’s agenda or objectives.

• Evaluate how perspectives are framed, especially if controversial topics are presented.

Documentaries: Primary or Secondary Sources?

Documentaries can be classified as either primary or secondary sources based on their content, purpose, and context. Their dual nature highlights the importance of critical evaluation before incorporating them into research. By understanding their intent and verifying their credibility, you can make the most of documentaries in your academic or professional projects.
