Longer essays may also contain an introductory page that defines words and phrases of the essay's topic. Most academic institutions require that all substantial facts, quotations, and other porting material in an essay be referenced in a bibliography or works cited page at the end of the text. This scholarly convention helps others (whether teachers or fellow scholars) to understand the basis of facts and quotations the author uses to support the essay's argument and helps readers evaluate to what extent the argument is supported by evidence, and to evaluate the quality of that evidence. The academic essay tests the student's ability to present their thoughts in an organized way and is designed to test their intellectual capabilities.
Perhaps you have been assigned a comparative essay in class, or need to write a comprehensive comparative report for work. In order to write a stellar comparative essay, you have to start off by picking two subjects that have enough similarities and differences to be compared in a meaningful way, such as two sports teams or two systems of government. Once you have that, then you have to find at least two or three points of comparison and use research, facts, and well-organized paragraphs to impress and captivate your readers. Writing the comparative essay is an important skill that you will use many times throughout your scholastic career.
