Before using this guide check with your faculty, school or department for their specific referencing guidelines
Generally, in academia, you should not use dictionary or encyclopaedic entries as citation sources. They are usually considered background reading material. Citing Medicine: The NLM Style Guide for Authors, Editors, and Publishers (2nd edition) only includes examples of citing the complete dictionary or encyclopaedia.
Include the DOI at the end of the reference if it is available.
