Information Services at Nottingham has a useful resource for learning how to cite and how to provide accurate references. There is also a useful set of links provided by Leeds University Library pointing to sites covering the Harvard, Numeric, Modern Language Association (MLA) and American Psychological Association (APA) referencing systems. The site also covers electronic sources.

Although the Harvard and Numeric styles are common, not all subjects are covered by these systems, so check your course handbook or faculty office for details of the referencing systems in use. Whatever you use, be consistent and stick to one method.
