Vancouver
This is the Vancouver style for referencing, used at the Univerity of Portsmouth within the School of Pharmacy and Biomedical Sciences and the Radiography departments.
This guide is modelled on Citing Medicine: The NLM Style Guide for Authors, Editors, and Publishers (2nd edition). You may wish to consult this source directly for additional information or examples.
Referencing a whole edited book is uncommon. You are more likely to be referencing individual chapters as you need to recognize the contributor whose work you are using. Even an introduction may be treated as a chapter. It is fine to have several chapters from one single edited book in your bibliography all recognized as separate entities.
