Complete Vancouver Citation Style Guide

Vancouver style is the standard citation system for biomedical and health sciences research. Developed by the International Committee of Medical Journal Editors (ICMJE), it uses numbered citations in brackets, allowing for concise in-text references and detailed reference lists. This comprehensive guide covers Vancouver style for all source types.

Understanding Vancouver Style

Vancouver style emphasizes efficiency in scientific writing through:

• Numbered citations [1], [2], [3] in the text
• Citation numbers assigned in order of appearance
• Numbered reference list arranged by citation order (not alphabetically)
• Specific formatting for journal abbreviations and publication details
• Concise presentation suitable for scientific papers

Basic Format

In-Text Citation

Citations appear as numbers in square brackets in order of appearance:

First citation: [1]
Second citation: [2]
Multiple citations: [1, 3, 5] or [1-3, 5]

Example:

Research shows that modern technology transforms organizations [1, 2]. A longitudinal study examined this effect [3].

Reference List Format

References are numbered in order of appearance, not alphabetically:

1. Author Surname Initial(s), Author Surname Initial(s). Title of article. Journal Abbreviation. Year;volume(issue):pages.

Example:

1. Smith J, Jones R. Digital transformation in organizations. J Bus Stud. 2024;45(3):234-256.

Key Vancouver Characteristics

• Journal abbreviations (not full titles)
• No quotation marks around article titles
• Period separates major elements
• Initials only for author first names
• Numbers assigned in citation order
• Reference list numbered 1, 2, 3… (not alphabetized)

Citation Order and Numbering

Citations are numbered in the order they first appear in the text:

Text: First mentioned source [1], then another source [2], then first source again [1].

Reference list:
1. First mentioned source
2. Second mentioned source

Never rearrange numbers; maintain appearance order.

Journal Title Abbreviation

Vancouver requires abbreviated journal titles (not full names):

Not: Journal of Business Studies
Abbreviated: J Bus Stud

Check PubMed for correct abbreviations.

Book Citations

1. Author Surname Initial(s). Title of Book. Edition (if not first). Place: Publisher; Year.

Example:

1. Adams J. Modern Research Methods. 2nd ed. New York: Academic Press; 2024.

Chapter in Edited Book

1. Author Surname Initial(s). Title of chapter. In: Editor Surname Initial(s), editor. Title of Book. Edition (if not first). Place: Publisher; Year. p. pages.

Website Citations
