Vancouver Referencing Example – Complete Guide for Students

Vancouver referencing is a widely used citation style in medical, healthcare, nursing, and biomedical subjects. It follows a numbered referencing system where sources are cited in the text using numbers that match a detailed reference list at the end of the document. This style is commonly used because it keeps academic writing clear, organised, and easy to read.

The Vancouver style was developed for scientific and medical publishing and is now used across universities, research institutions, and professional journals worldwide. It is also commonly followed by many UK universities for healthcare and medical-related academic courses. It provides a consistent structure for referencing books, journal articles, websites, online reports, and other academic sources.

This complete guide explains how Vancouver referencing works, including its rules, in-text citations, reference list formatting, and examples for different source types. It also highlights common referencing mistakes and useful tips to help students use the Vancouver style correctly in academic writing.

What is the Vancouver Referencing Style?

Vancouver referencing is a numbered citation system used predominantly in the biomedical sciences. Instead of inserting an author’s surname and publication year within the text (as you would in APA or Harvard styles), Vancouver uses a sequential number. Each number corresponds to a full citation in a reference list at the end of the document. In the UK, this referencing style is commonly used in medical, nursing, pharmacy, and healthcare-related courses across many universities.

The system was formalised through the International Committee of Medical Journal Editors (ICMJE), which issued guidelines known as the Uniform Requirements for Manuscripts Submitted to Biomedical Journals. These guidelines have since evolved into what practitioners recognise today as the Vancouver style. Due to its clear and structured format, Vancouver referencing is widely accepted in UK academic and clinical research writing.

List of Vancouver Referencing Examples for Different Sources

The examples below show how Vancouver referencing is used for books, journal articles, websites, online sources, and multiple authors in academic writing across UK universities and healthcare subjects.

1. Books

Books are among the most commonly cited sources. The Vancouver format for books follows a clear pattern:

Format: Author(s) Surname Initials. Title of Book. Edition (if not first). Place of publication: Publisher; Year.

Single Author Book

Kumar P, Clark M. Kumar and Clark’s Clinical Medicine. 10th ed. Edinburgh: Elsevier; 2020.

Multiple Author Book

Tortora GJ, Derrickson BH. Principles of Anatomy and Physiology. 15th ed. Hoboken: Wiley; 2017.

Edited Book

Gillman MW, Poston L, editors. Maternal Obesity. Cambridge: Cambridge University Press; 2012.

Chapter in an Edited Book

Phillips SJ, Whisnant JP. Hypertension and stroke. In: Laragh JH, Brenner BM, editors. Hypertension: Pathophysiology, Diagnosis and Management. 2nd ed. New York: Raven Press; 1995. p. 465-78.

2. Journal Articles

Journal articles are the most frequent citation type in scientific and medical writing. Pay close attention to abbreviated journal titles and correct formatting of volume, issue, and page numbers.

Format: Author(s) Surname Initials. Title of article. Abbreviated Journal Title. Year; Volume(Issue): Page-range.

Standard Journal Article

Rose ME, Huerbin MB, Melick J, Marion DW, Palmer AM, Schiding JK, et al. Regulation of interstitial excitatory amino acid concentrations after cortical contusion injury. Brain Res. 2002;935(1-2):40-6.

Article with DOI

Bhatt DL, Steg PG, Miller M, Brinton EA, Jacobson TA, Ketchum SB, et al. Cardiovascular risk reduction with icosapentaenoic acid for hypertriglyceridemia. N Engl J Med. 2019;380(1):11-22. doi:10.1056/NEJMoa1812792.

Organisation as Author

Diabetes Prevention Program Research Group. Hypertension, insulin, and proinsulin in participants with impaired glucose tolerance. Hypertension. 2002;40(5):679-86.

3. Websites

Websites present unique referencing challenges because content can change or disappear. Vancouver requires you to record the date you accessed the site, as well as any available publication or update date.

Format: Author(s)/Organisation. Title of page/document [Internet]. Place of publication: Publisher; Year [updated Year Mon DD; cited Year Mon DD]. Available from: URL

Organisation Website

World Health Organisation. Cardiovascular diseases (CVDs) [Internet]. Geneva: WHO; 2021 [cited 2024 Mar 15].

Government Website

National Institute for Health and Care Excellence. Hypertension in adults: diagnosis and management [Internet]. London: NICE; 2019 [updated 2023 Nov; cited 2024 Feb 20].

Always capture the URL carefully. If the webpage URL is very long, try to link to the homepage or a stable landing page and note the access path in your citation.

4. Online Sources

Beyond standard websites, students frequently need to cite online databases, online journal articles, digital repositories, and other electronic resources. The Vancouver approach adapts well to these formats.

Online Journal Article

Forouzanfar MH, Liu P, Roth GA, Ng M, Biryukov S, Marczak L, et al. Global burden of hypertension and systolic blood pressure of at least 110 to 115 mm Hg, 1990-2015. JAMA [Internet]. 2017 [cited 2024 Jan 10];317(2):165-82.

Database Entry

National Library of Medicine. MEDLINE [Internet]. Bethesda (MD): NLM; 2024 [cited 2024 Mar 30].

5. Multiple Authors

Handling multiple authors correctly is essential in Vancouver referencing. The rules differ depending on the number of authors listed on the source.

Two Authors

Tortora GJ, Derrickson BH. Principles of Anatomy and Physiology. 15th ed. Hoboken: Wiley; 2017.

Six Authors

Vasan RS, Beiser A, Seshadri S, Larson MG, Kannel WB, D’Agostino RB, Levy D. Residual lifetime risk for developing hypertension in middle-aged women and men: The Framingham Heart Study. JAMA. 2002;287(8):1003-10.

Seven or More Authors (et al.)

Understanding the correct author formatting rules helps students avoid common referencing mistakes and ensures their work follows proper Vancouver referencing conventions.

Why Students Use Vancouver Referencing

Students in health-related disciplines often find Vancouver referencing appealing for several reasons. Once understood, the system is elegant in its simplicity: numbers replace lengthy parenthetical citations, keeping prose clean and readable for a medical or scientific audience.

Key Reasons Vancouver Is Preferred

Clarity and readability: Numbered citations do not interrupt sentence flow
Standard in medical publishing: Most medical journals require the Vancouver format
Easy to verify: Readers can quickly jump to the numbered reference list
Consistent structure: Once you learn the format for one source type, others follow a similar logic
Reduces repetition: The same source keeps the same number throughout the entire document

Note: If you are submitting work to a medical school, nursing programme, or allied health course, there is a strong chance your institution expects Vancouver referencing. Always check your assignment brief or style guide before you begin writing.

Key Rules of Vancouver Referencing

Understanding the foundational rules helps you apply the system consistently. Below are the principles you must follow.

1. Sequential Numbering

Citations are numbered in the order they first appear in your text, beginning with 1. If you cite the same source again later, you use the original number assigned to it.

2. Superscript or Brackets

The citation number appears either as a superscript (raised above the line of text) or enclosed in round brackets, depending on your institution’s preference. Both are acceptable in Vancouver, but you must be consistent throughout your document.

3. Placement of Citation Numbers

Citation numbers are placed at the end of the sentence or clause to which they relate, after any punctuation such as a full stop or comma. They should appear as close as possible to the information being cited.

4. Author Names

In the reference list, authors’ surnames are followed by initials without full stops. List up to six authors. If there are more than six authors, list the first six followed by “et al.”

5. Journal Titles

Journal titles are abbreviated according to MEDLINE/PubMed standards. For example, The Lancet becomes Lancet, and The British Medical Journal becomes BMJ. Always check an abbreviation list if unsure.

6. Page Numbers

When referencing specific pages in a book or journal article, include the page range using a hyphen. Abbreviate second numbers where possible (for example, 123-8 rather than 123-128).

Common Vancouver Referencing Mistakes to Avoid

Even experienced students make errors when referencing. Being aware of the most frequent mistakes will save you marks and maintain academic credibility.

Assigning a New Number to a Repeated Source: Always reuse the original number for any source cited again.
Alphabetising the Reference List: Order references by first appearance in the text only.
Using Full Journal Titles: Always abbreviate journal titles to MEDLINE standards.
Listing More Than 6 Authors Without et al: After 6 authors, write et al. immediately.
Omitting the Access Date for Websites: Always include [cited Year Mon DD] for all online sources.
Using Harvard-Style (Author, Year) in Text: Vancouver uses numbers only, never author-year in text.
Forgetting Edition Information for Books: Always include the edition if it is not the first.
Inconsistent Superscript vs Bracket Style: Choose one format and use it throughout the whole document.

Tips to Improve Your Referencing Accuracy

Accurate referencing is a skill developed over time. These practical strategies will help you build good habits and avoid common pitfalls.

Keep a Running Reference List: As you gather sources during your research phase, record their full citation details immediately. Do not leave this until after you have finished writing. Trying to reconstruct citation information after the fact wastes time and often results in errors.
Use a Consistent Tracking Method: Whether you use a spreadsheet, a word-processor table, or a reference management tool, maintain a log of each source alongside the number you assigned to it. This prevents duplication and ensures consistency.
Verify Journal Title Abbreviations: Use the National Library of Medicine’s journal abbreviation database or the ICMJE list to confirm every abbreviated journal title. Incorrect abbreviations are a common reason for deducted marks.
Check Institutional Requirements: Some universities and journals have minor variations on the standard Vancouver style. Always read your course handbook or journal submission guidelines before finalising your reference list.
Proofread Reference List Separately: Treat your reference list as a document in its own right. Read it line by line, checking punctuation, spelling of author names, and numerical order independently of the rest of your work.

Vancouver Referencing Tools and Resources

Several tools can simplify the Vancouver referencing process, though you should always check automatically generated references against manual standards before submitting work.

Reference Management Software

Zotero: Free, open-source software that supports Vancouver style and integrates with Microsoft Word
Mendeley: A widely used academic reference manager with Vancouver output options
EndNote: A comprehensive tool popular in academic and research settings, with full Vancouver support
RefWorks: Cloud-based reference manager often provided by universities through library access

Online Citation Generators

Various websites allow you to input source details and generate a Vancouver-formatted reference automatically. These are useful for checking your manually written references, but always verify the output carefully since automated tools occasionally produce errors.

Authoritative Style Guides

ICMJE Recommendations: The foundational document for Vancouver style, available at icmje.org
Citing Medicine (NLM): The National Library of Medicine’s comprehensive guide, freely available online
Your institution’s library guide: Most university libraries publish their own Vancouver guide

Important: Reference management software and online generators are helpful aids, but they are not infallible. Always review every generated reference against the official Vancouver guidelines before submission.

Frequently Asked Questions

1Q. Do I have to use superscripts, or can I use brackets?

Either is acceptable under Vancouver style. Superscripts are more common in printed medical journals, while brackets are often easier to manage in word-processed student assignments. Check your institution’s preference and apply it consistently.

2Q. What do I do if a source has no author?

If no individual author is listed, begin the reference with the name of the organisation responsible for the content, or with the title of the document if no organisation is identifiable.

3Q. Can I cite secondary sources in Vancouver?

You should always try to locate and cite the original (primary) source. If the original is genuinely inaccessible, you may cite a secondary source, but you must make clear in your reference that you are doing so. Overuse of secondary citations is generally discouraged in academic writing.

4Q. How do I reference a source with no date?

If no publication date is available, write date unknown in the position where the year would normally appear. For websites, you should still include the access date.

5Q. Do I include a URL for journal articles I accessed online?

If the article is available in print form (i.e., it has a volume, issue, and page numbers), you do not need to include the URL. If the article only has a DOI, include that. Reserve URLs for sources not available in any other form.
