When referencing a piece of work using the Harvard system, a list of all the sources cited in the text should be added to the end. This list takes the place of a bibliography and should provide all the details necessary for a reader to find and consult any of the sources used. Each entry should thus include:
- The name of the author
- The title of the work
- The name of the collection, journal etc in which it appears, if relevant
- The date of publication
- The place of publication
- The publisher
The reference list entries should be listed alphabetically by the surnames of the authors or editors.
Where there are several works by the same author, they should be listed in date order, oldest first. Where there are a number of works produced by the same author in the same year, they should be distinguished with the addition of a lower case letter after the date e.g. '1989a'.
