There are thousands of citation styles in use. Your lecturer 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 different citation styles. Here's the information we want to reference:
Title: From Content to Context: The Evolution and Growth of Data Quality Research
Journal: ACM Journal of Data and Information Quality
We will demonstrate how this appears in two different referencing systems, namely Harvard (an inline style) and IEEE (a numbered style).
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.
It is important to note that there are many variations of the Harvard style, so always check if there is a specific one that is required.
The Library has books on these (and other) styles available to guide students on how to reference correctly.
Here's our example in the Harvard style. It is important to note that there are many variations of the Harvard style, so always check if there is a specific one that is required.

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.
Here's our example in the IEEE style.
