Vancouver style is used widely to cite biomedical information. It was originally set forth in 1978 by a group of editors from major biomedical journals who met in Vancouver, British Columbia—which is why it is called Vancouver Style. The style is recommended by the International Committee of Medical Journal Editors in the publication Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals.
The rules for using the style can be found in the following free ebook available from the PubMed bookshelf:
