Citation Styles Print Page

Why cite?

You must provide in-text citations and a bibliograhy or reference list whenever you quote or paraphrase ideas from other authors, in order to:

  • provide evidence for your arguments and add credibility to your work. It shows that you have sought out and considered a variety of viewpoints on a given topic.
  • show the depth and scope of your research and give credit to authors for their ideas.
  • help readers to locate and further explore the sources you consulted.
  • avoid charges of plagiarism.

Which sources to cite?

  • Direct quotations from a book, article, film, letter, email, lecture, etc.
  • Ideas you draw from a source but present entirely in your own words.
  • Facts or ideas which are not common knowledge.
  • Not just books and articles but statistical data, websites, blogs, etc.
