Understanding the Sources of History

Historians build accounts of the past from sources, which are the traces people left behind. A sources of history concept map divides this evidence into primary sources, created at the time by witnesses or participants, and secondary sources, written later to interpret them. Most map branches then cover document types, physical remains and how each source is checked.

  • Primary sources: letters, diaries, photographs, official records, artifacts
  • Secondary sources: textbooks, scholarly articles, biographies, documentaries
  • Tertiary sources: encyclopedias and reference works that summarize other sources
  • Source criticism: testing authorship, date, bias and reliability
  • Archives: where original records are stored and accessed

Use the map to revise how each source type is used and judged. CogniGuide can build a personalized version from your own notes, so your map matches your course.

Sources of History Questions

Answers on historical sources and building your own map.

What is the difference between a primary and a secondary source?

A primary source was created during the period studied, such as a letter or a photograph. A secondary source analyzes or interprets primary sources, such as a history book written decades later.

Why do historians check the reliability of sources?

Sources can reflect the bias, purpose or limited knowledge of their authors. Historians compare sources and check authorship and date to judge how much weight each deserves.

Which files can I use to make a source map?

You can upload PDF, Word (DOCX) and PowerPoint (PPTX) files, text or Markdown files, or images. You can also type a topic and let the AI build the map.

Is it free to create a sources of history map?

Yes. The free plan allows 5 creations a week with no payment needed, and paid plans raise those limits. You can also turn the map into a quiz.
