A summary is a shortened version of someone else's writing or thoughts. Summaries vary in length and amount of details depending on a teacher's requirements, the length of the original source (article, book, passage) and the purpose of the summary; however, all summaries must: · be shorter than the original source (article, book, passage) approximately one third the length of the original source; · include the main idea of the original source in your own words; · include major details (also known as supporting ideas) in your own words; · should not include your knowledge, ideas or opinion unless your teacher requests it. · identify the author, title of article, title of publication, where published, publisher, year of publication, and page information, at the top of the page of your summary (or in-text.)
