Introduction — What Vancouver Format Is and Who Uses It

Vancouver is a numeric author–number citation system that links in-text numbers to a numbered reference list. References are listed in the order they appear in the text, not alphabetically.

It is commonly used by authors and editors in medicine and health sciences, including clinical research, textbooks, and many peer-reviewed journals. Because websites often provide clinical guidelines, data, and policy statements, accurate website citations are essential.

General Rules — Key Formatting Rules

Use Arabic numerals (1, 2, 3…) in ascending order as citation identifiers.
Place the citation number in the text immediately after the fact, quotation, or sentence it supports. Use superscript or parentheses according to journal requirements.
Reference list entries must be numbered in the order cited in the text — not alphabetized.
Author names: surname followed by initials without periods or commas (e.g., Smith J).
For more than six authors, list the first six followed by "et al.".
Include medium and access details for web resources: use “[Internet]” after the title and provide a date cited and the full URL.

How to Cite by Source Type

Below are step-by-step templates and examples for common source types. Use code formatting for the citation examples to copy them easily.

1. Books

Template:

Author(s). Title. Edition. Place of publication: Publisher; Year.

3. Websites (step-by-step)

Website citations are often the most variable. Follow this ordered checklist:

In-Text Citations — Rules and Examples

In-text citations in Vancouver use numbers that correspond to the reference list. Use numbers in ascending order as sources appear in your text.

Common formats:

Superscript: "Recent trials show improved outcomes.^1"
Parentheses: "Recent trials show improved outcomes (1)."

Place the citation immediately after the clause or sentence that the citation supports. If citing multiple sources, list numbers separated by commas or a dash for ranges (e.g., 2,4,6 or 2–5).

Examples:

The incidence of disease has risen in recent years (3). Smith et al. found improved recovery times after intervention ^7.

Reference List — Formatting Rules and Example

Reference list rules:

Number entries sequentially in the order they are cited.
Use minimal punctuation: surname followed by initials (no full stops).
Titles: use sentence case (capitalize only the first word and proper nouns) for article and book titles, journal names abbreviated per Index Medicus.
Provide full page ranges, DOIs when available, and access dates for online material.

Sample reference list (first five entries):

1. Smith J, Brown P. Clinical Pharmacology. 3rd ed. London: Medical Press; 2018.
2. Lee K, Patel R, Singh A. New approaches to diabetes care. J Med Res. 2020 Nov 12;45(11):1234–40. doi:10.1000/jmr.2020.45

5. Nguyen T. Genetic markers in pediatric leukemia [dissertation]. Melbourne: University of Melbourne; 2017.

Common Mistakes — 3–4 Errors to Avoid

Incorrect author format: Do not write full first names or add periods. Use "Smith J" not "John Smith" or "Smith, J."
Wrong reference order: Vancouver requires numbering by order cited, not alphabetic ordering.
Missing access/cited date for web resources: Always include a [cited YYYY Mon DD] when citing online content.
Overlooking pagination or DOI: For journal articles include volume, issue, page range, and DOI if available to help retrieval.
