Vancouver Style Guide

Question 1

What is Vancouver style citation?

Answer

Vancouver style is a numeric citation system developed in 1978 by the International Committee of Medical Journal Editors (ICMJE). References are numbered consecutively in order of first appearance in the text and listed numerically in the reference list. It is the dominant citation style in biomedical and health sciences publishing, used by over 1,000 medical journals including The Lancet, BMJ, JAMA, and NEJM. SimpleFormat applies Vancouver rules automatically.

Question 2

What is the difference between Vancouver, ICMJE, and NLM style?

Answer

Vancouver, ICMJE, and NLM style are the same citation system. 'Vancouver' is the colloquial name from the 1978 meeting location. ICMJE (International Committee of Medical Journal Editors) maintains the recommendations. NLM (National Library of Medicine) publishes the detailed 'Citing Medicine' guide. All three terms refer to the same numeric citation format. SimpleFormat supports all Vancouver/ICMJE/NLM requirements.

Question 3

How do in-text citations work in Vancouver style?

Answer

In Vancouver style, citations are numbered consecutively in order of first appearance. Use Arabic numerals as superscripts (¹ ² ³) or in parentheses/brackets (1) (2) (3). When you cite a source again, reuse its original number. Example: 'Studies show¹ that treatment is effective.² Earlier research¹ confirmed this.' SimpleFormat auto-detects and formats citations correctly.

Question 4

Should I use superscript or brackets for Vancouver citations?

Answer

Vancouver style permits both superscript (¹ ² ³) and bracketed citations (1), [1], or (1). Choose one format and maintain consistency throughout your document. Most medical journals prefer superscript, but check your target journal's requirements. SimpleFormat supports all formats and ensures consistency.

Question 5

Where do citation numbers go in relation to punctuation?

Answer

In Vancouver style, citation numbers go AFTER periods and commas (e.g., 'results.¹' not 'results¹.'). Citation numbers go BEFORE colons and semicolons (e.g., 'results¹:' not 'results:¹'). This is a common error that SimpleFormat corrects automatically.

Question 6

How do I cite multiple sources at the same point in Vancouver?

Answer

Use commas for non-consecutive numbers (e.g., 1,3,5) and hyphens for 3 or more consecutive numbers (e.g., 1-5). For exactly 2 consecutive numbers, use commas only (e.g., 1,2 not 1-2). No spaces between numbers. Example: 'as reported previously.¹⁻⁵,⁷,⁹' SimpleFormat formats multiple citations correctly.

Question 7

How many authors should I list in Vancouver references?

Answer

The ICMJE standard is to list up to 6 authors, then add 'et al.' for additional authors. Some institutions permit listing only 3 authors before 'et al.' Note: 'et al.' is not italicized in Vancouver style. Example: 'Smith AB, Jones CD, Brown EF, et al.' SimpleFormat applies the correct author truncation rule.

Question 8

How do I format author names in Vancouver references?

Answer

Author names are formatted as Surname followed by Initials with no periods or spaces between initials. Example: 'Smith JA' not 'Smith, J.A.' or 'Smith J. A.' Multiple authors are separated by commas. SimpleFormat auto-formats author names to Vancouver standards.

Question 9

What is the correct order for Vancouver reference lists?

Answer

References must be numbered in order of first citation in the text, NOT alphabetically. This is a fundamental difference from APA, Harvard, and MLA styles. Reference 1 is the first source cited in your paper. SimpleFormat maintains correct numeric ordering.

Question 10

Do I reuse the same number when citing a source again?

Answer

Yes. Once a source is assigned a number (e.g., 3), you reuse that same number every time you cite it throughout the document. You never assign a new number to a previously cited source. SimpleFormat tracks citation numbers automatically.

Question 11

How do I cite a journal article in Vancouver style?

Answer

Format: Author(s). Article title. Abbreviated Journal Name. Year;Volume(Issue):Pages. doi:xxx or Available from: URL. Example: 'Smith AB, Jones CD. Treatment outcomes in diabetes. JAMA. 2024;331(5):412-8. doi:10.1001/jama.2024.1234' SimpleFormat formats journal citations correctly.

Question 12

Should journal titles be abbreviated in Vancouver?

Answer

Yes. Journal titles must be abbreviated according to NLM/MEDLINE standards. Example: 'New England Journal of Medicine' becomes 'N Engl J Med'. Use the NLM Catalog to find correct abbreviations. Full titles are only permitted if your institution specifically requires them. SimpleFormat uses NLM standard abbreviations.

Question 13

Are journal titles italicized in Vancouver style?

Answer

No. Unlike APA and MLA, Vancouver style does NOT require italics for journal titles. Journal titles are abbreviated and not italicized by default. Some institutions may prefer italics—this is a configurable option in SimpleFormat.

Question 14

How do I format page ranges in Vancouver?

Answer

Page ranges should be abbreviated by dropping repeated digits. Example: pages 123-129 becomes 123-9; pages 1234-1238 becomes 1234-8. For book chapters, use 'p.' prefix (e.g., p. 123-9). SimpleFormat auto-abbreviates page ranges.

Question 15

Do I include DOI or URL for journal articles?

Answer

Include DOI when available—it is preferred over URL. Format options: 'doi:10.xxxx/xxxxx' or 'https://doi.org/10.xxxx/xxxxx'. Place at end of reference. If no DOI exists, include URL with access date. SimpleFormat preserves DOIs in correct format.

Question 16

What access date format does Vancouver use?

Answer

Access dates use the format [cited YYYY Mon DD] with 3-letter month abbreviations. Example: '[cited 2024 Jan 15]'. Access dates are required for URLs but NOT required when a DOI is present. SimpleFormat auto-formats access dates.

Question 17

How do I cite an online-only journal article?

Question 19

How do I cite an epub ahead of print article?

Question 20

How do I cite a journal article with 7 or more authors?

Answer

List the first 6 authors followed by 'et al.' (not italicized). Example: 'Smith AB, Jones CD, Brown EF, White GH, Black IJ, Green KL, et al. Title. J Name. 2024;Vol(Issue):Pages.' SimpleFormat applies the 6 + et al. rule automatically.
