Writing Useful Summaries

Condense longer information accurately without losing meaning.

Understanding the topic

A summary communicates the most important points of a source in fewer words. It should retain the original meaning, avoid unnecessary details and not introduce unsupported claims.

Use the examples below as a starting point, then adapt the method to your own situation.

Step-by-step approach

Read the whole text; identify the main message; select key supporting points; write in your own words; compare with the source.

  1. Identify the purpose and information you need.
  2. Follow the recommended method carefully.
  3. Check your result against the original purpose.
  4. Revise anything unclear or incomplete.
