What is the Vancouver format and who uses it?

Vancouver is a numeric reference style commonly used in medicine, health sciences, and some life sciences. References are numbered in the text in the order they appear and listed numerically in the reference list.

Vancouver emphasizes concise author and title formatting, journal abbreviations (often per PubMed/MEDLINE), and clear details for electronic sources, including PDFs. When citing a PDF, you typically treat it as an electronic document and include format, availability, and access (citation) date information.

General Rules

Number references sequentially in the text (e.g., 1, 2, 3) using either superscript or brackets—be consistent.
List references numerically in the reference list in the same order they appear in text.
Author names: surname followed by initials without periods or commas (e.g., Smith J, Brown AB).
For journal articles include: author(s), title, journal abbreviation, year, volume(issue):pages.
For online PDFs indicate the medium and availability, e.g., [Internet], [PDF], Available from: URL, and the access (cited) date.
If more than six authors, list the first six followed by et al.

How to Cite by Source Type

The following step-by-step examples show how to format common PDF source types in Vancouver style. Use the code blocks for exact punctuation and order.

1. Book (PDF)

When a whole book is available as a PDF online, treat it as an electronic book. Include place of publication and publisher if present, then indicate [Internet] and [PDF], and provide the URL and access date.

Author AB, Author CD. Book title: subtitle. Place: Publisher; Year [cited YYYY Mon DD]. Available from: URL [PDF]

Example:

Doe J, Smith R. Clinical guide to respiratory care. London: HealthPress; 2018 [cited 2024 Aug 10]. Available from: https://example.org/respiratory/guide.pdf [PDF]

2. Journal Article (PDF)

If you download an article as a PDF from a journal website, cite it as a journal article and indicate that it was accessed online. Prefer journal abbreviations where available.

Author AB, Author CD. Article title. Abbrev J Title. Year;Volume(Issue):pages. [cited YYYY Mon DD]. Available from: URL [PDF]

Example:

Lee HJ, Patel S, Gomez P. Effectiveness of X therapy in elderly patients. J Geriatr Med. 2020;15(4):221-7. [cited 2024 Aug 10]. Available from: https://journalexample.org/article123.pdf [PDF]

3. Website PDF / Report

Government or organizational reports in PDF form are common. Treat them as reports and include corporate author if no individual authors are listed. Include [Internet] and [PDF] tags.

Organization name. Title of report. Place: Publisher (if different); Year [cited YYYY Mon DD]. Available from: URL [PDF]

Example:

World Health Organization. Global vaccine report 2021. Geneva: WHO; 2021 [cited 2024 Aug 10]. Available from: https://who.int/publications/global_vaccine_report_2021.pdf [PDF]

4. Thesis or Dissertation (PDF)

Dissertations or theses available as PDFs online should indicate the degree, institution, and [Internet]/[PDF] details.

Author AB. Title of thesis [doctoral thesis]. City: University; Year [cited YYYY Mon DD]. Available from: URL [PDF]

Example:

Nguyen T. Metabolic markers in diabetes progression [doctoral thesis]. Melbourne: University of Melbourne; 2019 [cited 2024 Aug 10]. Available from: https://repository.unimelb.edu.au/thesis_nguyen_2019.pdf [PDF]

5. Conference Paper (PDF)

For conference papers available as PDFs, include conference name, location, date and the PDF availability.

Author AB. Title of paper. In: Editor(s) (if any), editors. Title of conference; Year Month Day; City. Place: Publisher; Year. p. pages. [cited YYYY Mon DD]. Available from: URL [PDF]

Example:

Garcia M, Liu X. New approaches to neural imaging. In: Proceedings of the Int Conf Neural Eng; 2017 May 12-15; Boston. Boston: NeuralPub; 2017. p. 45-50. [cited 2024 Aug 10]. Available from: https://confsite.org/2017/garcia_neural_imaging.pdf [PDF]

In-Text Citations

Vancouver uses numbers to refer to sources. Use the number assigned in the reference list in the text at the point where the source is used.

Superscript example: The treatment improved outcomes in a randomized trial.^1
Bracketed example: The treatment improved outcomes in a randomized trial [1].

Place the citation number immediately after the relevant clause or sentence, after punctuation if it refers to the whole sentence. Use the same number each time you cite the same source.

Examples:

Recent studies show improved survival with therapy X [2].

Smith et al. reported increased efficiency in the device.^3

Reference List

The reference list contains complete citations in numeric order according to first mention in text. Do not alphabetize.

Basic formatting rules:

Start each reference with the number followed by a space and the reference text: 1 Author(s).
Use a hanging indent for each reference entry.
Use journal title abbreviations where applicable (consult PubMed abbreviations).
Include [Internet] and [PDF] for online PDFs, provide the full URL and the access/date in the form [cited YYYY Mon DD].

Sample reference list (short):

1 Doe J, Smith R. Clinical guide to respiratory care. London: HealthPress; 2018 [cited 2024 Aug 10]. Available from: https://example.org/respiratory/guide.pdf [PDF]
2 Lee HJ, Patel S, Gomez P. Effectiveness of X therapy in elderly patients. J Geriatr Med. 2020;15(4):221-7. [cited 2024 Aug 10]. Available from: https://journalexample.org/article123.pdf [PDF]
3 World Health Organization. Global vaccine report 2021. Geneva: WHO; 2021 [cited 2024 Aug 10]. Available from: https://who.int/publications/global_vaccine_report_2021.pdf [PDF]

Actionable tip: generate a first draft of your reference list with Rephrasely’s citation generator, then verify journal abbreviations and access dates manually.

Common Mistakes (and How to Fix Them)

Omitting [PDF] or [Internet] — If the source is an online PDF, mark it as such. Fix: add [Internet] and [PDF] plus the URL and a cited date.
Wrong author format — Vancouver requires surname then initials without periods. Fix: change "John A. Smith" to "Smith JA".
Listing authors incorrectly when >6 — Some writers list all authors; Vancouver commonly lists the first six then et al. Fix: list first six authors then "et al."
Inconsistent in-text numbering — Switching styles mid-text (e.g., author-date then numbers) confuses readers. Fix: renumber references in order of first appearance and update citations consistently.

Frequently Asked Questions

Do I always need to include the access (cited) date for a PDF?

Yes — for online PDFs, include the access or cited date in the format [cited YYYY Mon DD]. This documents when you retrieved the file and is important because web content can change or be removed.

Should I use journal title abbreviations for articles I downloaded as PDFs?

Yes — use standard journal abbreviations (as in PubMed) in Vancouver references. If you are unsure of the correct abbreviation, confirm via the journal’s site or PubMed. Rephrasely’s citation generator can speed this up but always verify abbreviations manually.

Can Rephrasely help format multiple citations in Vancouver style?

Absolutely. Use the Rephrasely citation generator to produce Vancouver-style citations. You can then refine entries and run your document through Rephrasely’s plagiarism checker, AI writer, or paraphraser for additional editing support.
