Before selecting a referencing style check with your tutor, lecturer or supervisor for the style preferred by the School or Department.

Introduction to the style

This version of the Vancouver style uses a numeric system of in-text referencing. A consecutive number is assigned to each reference as it is cited in the text. If a source is cited again in the text the reference number remains the same.

References are presented in two ways:

1. A reference list (or bibliography) at the end of the work.
2. In text citations.

Three major systems of in-text references can be used: citation-sequence, citation-name, and name-year. This guide refers only to the citation-sequence (numeric) system of in-text referencing. In this system numbers are used in the text to refer to the reference list.

In-text citations

• References are numbered in the order they first appear in the text.
• Assigned numbers are re-used each time a particular reference is cited.
• Citation numbers can be superscripts e.g. "…was the most significant.⁴" or in round brackets e.g. "…was the most significant.(4)".
• When citing multiple references join inclusive numbers using a hyphen e.g. (2-5). If numbers are non-inclusive separate with commas. e.g. (2,4,7,10).

Reference list

• A reference list should include all (directly quoted or paraphrased) sources cited, a bibliography should include all sources consulted, whether or not they are directly quoted or paraphrased.
• Entries are listed numerically (the same order that they are cited in the text).
• Capitalise only the first word of a title (as well as words that would normally begin with a capital letter).
• If no author or editor can be identified, begin the reference with the title.
• Commonly used words in publisher names may be abbreviated. For example: Dept. for Department.
• Place of publication:
  • If the publisher is located in more than one city: cite the city that is printed first.
  • For cities that are not well known follow with the country name either written out in full or as the ISO country code. For example: Melbourne (Australia) OR Melbourne (AU).
  • If no place of publication can be found but can reasonably be inferred, place the city in square brackets. e.g. [Melbourne].
• If no publisher can be found, use [publisher unknown].
• If no date of publication can be found, use the copyright date preceded with ‘c’ c2010. If no copyright date can be found, use [date unknown].
