One of the major features of academic writing is acknowledging the books, journal articles and other information sources that you have used, usually by citing them one-by-one in your assignment and listing them all at the end in a bibliography. Often there are many marks for doing this correctly so it is a skill worth learning as soon as you can.
If you don't acknowledge your sources you might pass off someone else's ideas, quotations etc. as your own. This is plagiarism which is not permitted by the university and can have serious consequences for you.
