Guidelines for Summarizing Sources


Another good skill to help you incorporate research into your writing is summarizing. Summarizing is to take larger selections of text and reduce them to their basic essentials: the gist, the key ideas, the main points that are worth noting and remembering. Think of a summary as the “general idea in brief form”; it's the distillation, condensation, or reduction of a larger work into its primary notions and main ideas.

As with directly quoting and paraphrasing, summarizing requires you to cite your sources properly to avoid "accidental" plagiarism. moreover, a summary should not change the meaning of the original source. a good summary should be a shortened version that conveys the purpose and main points of the original source.

Examples of Good and Bad Summaries

Be careful when you summarize that you avoid stating your opinion or putting a particular bias on what you write. This point is important because the goal of a summary is to be as factual as possible.
For example, here is an example of an inaccurate, opinion-laden summary about Pixar’s popular movie Finding Nemo:

So there's a film where a man's wife is brutally murdered by a serial killer and his son is left physically disabled. In a twist of events, the son is kidnaped and kept in a tank while his father chases the kidnapper thousands of miles with the help of a mentally challenged woman. Finding Nemo is quite the thriller.

This example is a bad summary because it is very vague, and it contains the writer’s opinion as well as twists the events of the story into something it is not. Pixar’s Finding Nemo is not a thriller or a horror story like described above—it is an animated children’s movie about fish.

Here is a better summary of Finding Nemo:

Pixar’s Finding Nemo (2003) is a story about Marlin, a clownfish, who is overly cautious with his son, Nemo, who has a damaged fin. When Nemo swims too close to the surface to prove himself, he is caught by a diver, and horrified Marlin must set out to find him. A blue reef fish named Dory, who has a really short memory, joins Marlin and together they encounter sharks, jellyfish, and a host of ocean dangers. Meanwhile, Nemo plots his escape from a dentist's fish tank where he is being held. In the end, Marlin and his son Nemo are reunited, and they both learn about trust and what it means to be a family.
