Here are some steps you can take to form a good summary.
On to the next page for structuring your summary.
STRUCTURING YOUR SUMMARY
Most teachers look for the following elements in a summary. The length of a summary depends on how much development you need: development refers to direct quotes, examples, paraphrases or reasoning.
Include the following things in your first paragraph:
full name of the author
title of the source (in quotes if an article, underlined if a book)
date of publication (either in parentheses or in the sentence)
background information regarding the publication
the social significance of your thesis (the “so what”)
This paragraph and the others that follow it form the body of the paper. Each has to directly support your focus. It's a big mistake to just retell the story or article. The prof has already read this source: what the prof doesn't know is your focus, your opinion about it. Body paragraphs usually have this structure:
smaller version of the focus
quote or reasoning or example or paraphrase
explanation or opinion
Many writers omit their own opinions and their own reasoning: if this sounds like you, start reading book reviews in The New York Times Sunday book review section. Then you'll see how reviewers integrate their own opinions with the facts of the source.
Other writers have all opinion and no facts from the article or book. If this sounds like you, think about having at least 1-2 quotes or paraphrases per page of text.
There are many ways to end your summary. One way is to point toward the future. Another way is to say why this article was so important. Another is to repeat what you said earlier. Reread the entire thing and something will usually hit you as the best way to finish.
