At the University of Cumbria most subject disciplines use the Cite them right version of Harvard referencing system. Check the Referencing and Avoiding Plagiarism webpages for information about referencing systems for other subject disciplines.
Even if you have used Harvard before, it is likely that it differs from the system we use at the University of Cumbria. To reference in accordance with the University guidelines, follow the format set out in Pears and Shields (2019). There are several copies available in the library; alternatively, you can access an online version of the book.
