There are thousands of citation styles in use. Your lecturer, course director or supervisor may tell you to use a particular one, or allow you to choose one on your own.
Guides for each style will tell you how to format the references:
Many different styles are in use in Trinity College Dublin - for definitive answers you should use the full style manual for each system.
We are going to see what a reference looks like using using different citation styles. Here's the information we want to reference:
We demonstrate how this appears in a variety of different referencing systems, namely the APA 7th Edition, MLA 8th Edition, Vancouver; and Chicago 17th Edition.
Inline citations use a brief summary of the reference in the text (such as listing the author and date, or the author and title, or author and page) with the full reference stated at the end of the chapter or work.
This final list is called a reference list or bibliography.
Generally the full list of references will be in alphabetical order by the first author’s surname.
Inline styles are sometimes called the “Harvard” style as they were first used at Harvard in the 1880s. They are also called “Parenthetical” styles as they enclose the partial information in brackets.
Two of the most popular Harvard-type styles are the APA 7th Edition, and the MLA 8th Edition. Our example is used to show the similarities and differences below.
The Library has books on these (and other) styles available to guide students on how to reference correctly.
"Referencing, like research and other academic learning skills, has often not been taught explicitly, or within a discipline context prior to tertiary education" (Stagg et al., 2013).

"As the global information landscape increasingly facilitates the sharing, re-purposing and dissemination of information, the ways in which students are accustomed to interacting with information resources are also changing" (Stagg et al.).

Numbered styles list references in the order they are mentioned, using a digit in the text to refer to the fuller citation at the end.
If a reference is mentioned again later, it reuses the same number.
The most common numbered style is Vancouver - while this style has its own particular rules, numbered styles in general are often referred to as Vancouver styles.
Here's our example in the Vancouver style, using the "official" rules given by the NLM/PubMed.

Like numbered styles, footnote styles give the reference an ascending number in the text and the full references are listed in that order at the bottom of the page in a footnote. A full list at the end of the work or chapter may also be required - although unlike with numbered styles, this may be in alphabetical order by surname, rather than in order of mention.
The Chicago style is the most well-known footnote style. In Chicago and other footnote styles there are rules that apply if you use a work again in another footnote. Up until the Chicago 16th Edition, If you mention the citation again as the next footnote, then the term “ibid” (“in the same place”) is used instead of the reference. If it is used again after referring to a different citation, then a short form of the reference is used in the footnotes - the manual for the style will tell you what this should look like. However, this was changed in the Chicago 17th Edition, with the short form now favoured over ibid even if mentioned immediately afterwards.
