How to Write a Summary

Summarizing consists of two important skills:

  1. identifying the important material in the text, and
  2. restating the text in your own words.

Since writing a summary consists of omitting minor information, it will always be shorter than the original text.

How to Write a Summary

  • A summary begins with an introductory sentence that states the text’s title, author and main thesis or subject.
  • A summary contains the main thesis (or main point of the text), restated in your own words.
  • A summary is written in your own words. It contains few or no quotes.
  • A summary is always shorter than the original text, often about 1/3 as long as the original.  It is the ultimate “fat-free” writing.  An article or paper may be summarized in a few sentences or a couple of paragraphs. A book may be summarized in an article or a short paper.  A very large book may be summarized in a smaller book.
  • A summary should contain all the major points of the original text, but should ignore most of the fine details, examples, illustrations or explanations.
  • The backbone of any summary is formed by critical information (key names, dates, places, ideas, events, words and numbers). A summary must never rely on vague generalities.
  • If you quote anything from the original text, even an unusual word or a catchy phrase, you need to put whatever you quote in quotation marks (“”).
  • A summary must contain only the ideas of the original text. Do not insert any of your own opinions, interpretations, deductions or comments into a summary.
  • A summary, like any other writing, has to have a specific audience and purpose, and you must carefully write it to serve that audience and fulfill that specific purpose.
