Citing (in-text) and referencing (providing the full details of the source cited, usually at the end of your writing) is a standardised way of acknowledging materials used in your research. Ask your lecturer if you are unsure which style to use.
For information and resources about the most popular styles, check out our Citation Styles Guide.
A reference is not only the way we identify a source of information we have used, it is also a way that we can locate a source of information.
While you are studying, you will need to find and use references, and cite and reference the information you use.
Parts of a reference include:
References are formatted differently, depending on the referencing style used. Here is a break-down of an example of a journal article reference in the APA (American Psychological Association) style:
Jerrentrup, A., Mueller, T., Glowalla, U., Herder, M., Henrichs, N., Neubauer, A., & Schaefer, J. R. (2018). Teaching medicine with the help of “Dr. House”. PLoS ONE, 13(3), Article e0193972. https://doi.org/10.1371/journal.pone.0193972
The authors are listed first, last name followed by initials.
The year of publication is written after the authors, in brackets.
The title is next, e.g.; article title, book or book chapter, webpage, documentary, etc.
Next is the name of the wider source if there is one (in APA it is written in italics), e.g.; this is where you would write the title of a journal that an article is found in, or the title of a book that a book chapter is in.
For journal articles, this is where you write the journal number (in italics), followed by the journal issue (in brackets).
Next, the page numbers, or the article number is written; like it is in this example.
Finally, the DOI or an URL is included, because this is how we find the resource online.
NB: Full stops, commas, brackets and italics are all part of the referencing style, and will differ according to the particular style you are using or reading.
References will also differ depending on the source of your information, e.g., a webpage won’t have page numbers, or if you are citing a physical book, you would write the publisher last, instead of a DOI or URL.
Citing and referencing the ideas and research you use in your assignments is a critical part of all academic work because it:
Citing and referencing avoids plagiarism by giving you a way to correctly attribute credit to other authors or researchers.
