4.1 Primary Vs Secondary Sources
Primary Sources: These are immediate, first-hand accounts or original information directly
related to your research topic. Examples include diaries, speeches, original manuscripts, articles
and photographs. Primary sources provide direct evidence about the people, events, or
phenomena being studied. They are essential for making new discoveries, providing credible
evidence, and offering authoritative information for your arguments.
Secondary Sources: These sources are one step removed from primary sources and include
works that describe, interpret, analyse, or evaluate information from primary sources. Examples
of secondary sources are books, documentaries, and critical analyses. Secondary sources add a
layer of interpretation and analysis to the information found in primary sources. They are
valuable for gaining a comprehensive overview of your topic, understanding how other
researchers have approached it, and supporting or contrasting your arguments with existing
research
