Quoting and paraphrasing
The most common way of using previous research is by paraphrasing or summarising, which means retelling something using your own formulations.
Usually the main point of a source is summarised. You can summarise a paragraph, a whole chapter or even an entire book. When you paraphrase, be careful not to simply change a few words into synonyms. One way to begin is to find the main point of the passage or chapter you want to summarise. Highlight or underline key words, phrases or definitions that must be used in order for the reader to understand. Then put the original text away, and write a paraphrase in your own words, using the main point and the key words you identified.
Quotations
When you quote, you report word by word what somebody has written or said. However, quotes should be used sparingly. A quotation must serve a purpose. You should be able to justify the inclusion of all quotations. Why are you quoting and not paraphrasing? If you paraphrase a passage or summarise a longer text, it shows that you have understood the original text and that you are using your sources skilfully.
