• A small group of editors of general medical journals met informally in Vancouver, British Columbia, in 1978 to establish guidelines for the format of manuscripts submitted to their journals.
• This group became known as the Vancouver Group. Its requirements for manuscripts, including formats for citations and references were first published in 1979 by the National Library of Medicine (NLM).
• The Vancouver Group expanded and evolved into the International Committee of Medical Journal Editors (ICMJE), which meets annually.
