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.
In Vancouver your bibliography is arranged in numerical order, so you should just have one long numerical sequence containing everything you've used. Do not list books, journals, etc. separately.
