You can summarize, paraphrase and quote sources of information.
Summarizing – When writing a summary, you find the most important ideas in a text and restate them in your own words in shortened form.
Paraphrasing – Paraphrasing is restating someone else’s ideas in your own words—not necessarily shortened.
Quoting – Use quotes to back up your main points. Every quotation should be introduced and integrated into your essay to show the relationship between the quotation and your own ideas. When you use a quote, you should always explain what the quote means in relation to what you are trying to explain.
Don’t forget that whether you are quoting, summarizing or paraphrasing, you must tell your reader where and/or from whom you got your information from.
