The Vancouver referencing style is widely used in scientific and medical papers. But how do you cite an online video, such as a YouTube video, in this system? In this post, we\u2019ll look at how to format both in-text citations and the reference list entry for an online video.\n\nCiting an Online Video in Vancouver Referencing\n"Vancouver referencing" is another term for a number\u2013endnote referencing. As such, you cite sources in the text with a bracketed number:\nHigh glucose levels can lead to damaged blood vessels (1).\nThe number here points to an entry in the reference list at the end of your document, with sources numbered in the order you first cite them. The citation above, for instance, would be for the first source cited in the document and the first source in the reference list.\nIn addition, since a video does not have page numbers, you may need to use a timestamp in citations if you quote something. This can go after the citation number, such as in the following:\nThis approach to treatment is called "weight optimization" (2: 00:14:13).\nHere, the quote comes from 14 minutes and 13 seconds into the video.\nOr, if you have named the video creator in the text, you can give the citation number immediately afterwards and the timestamp in a separate set of brackets after the quotation. For example:\nHasudungan (1) says that "ATP is energy" (00: 04: 51).\nIn this case, we're quoting something from four minutes and 51 seconds into the video. Anyone who wanted to check the quotation would then be able to find it by looking up the full source information in your reference list.\n\nOnline Videos in a Vancouver Reference List\nIn Vancouver, the reference list format for an online video is:\n(Citation Number) Uploader Surname and Initials\/Username. Title of Video [Video]. Year uploaded. Available from: URL [Accessed Date].\nIn practice, then, a reference for a YouTube video would look like this:\n(1) Hasudungan A. Diabetes Complication and Pathophysiology of the Complication. [Video]. 2016. Available from: https:\/\/www.youtube.com\/watch?v=ZnnVUq1P5Yo [Accessed June 22, 2020].\nIf you do not know the real name of the uploader, though, you can give their username instead. For instance:\n(2) University of California Television. Making Sense of Diabetic Medication [Video]. 2014. Available from: https:\/\/www.youtube.com\/watch?v=pQHX-SjgQvQ [Accessed June 22, 2020].\n\nVancouver Referencing Variations\nVancouver referencing is a style rather than a formal system. As such, there are many versions of Vancouver available.\nThe version we use in this post is based on Imperial College London\u2019s style guide [PDF], but make sure to check your own style guide if you have one.\nAnd if you would like a little extra help to check the referencing in your documents, and every other aspect of your writing, why not upload something for professional proofreading today?
