Know your referencing style Find out which referencing style your lecturers are expecting you to use, and which style manual or guide is recommended. Some Schools have their own referencing guides.
Identify your source What are you trying to reference? Is it a book, an ebook, an article, an online article, a conference report, a website, or something else? The type of document you have dictates the details you must use in your reference.
Collect the referencing details Write down the details you need to include in a reference for your document (i.e. author/s, year, book title, edition, article title, journal title, volume number, page numbers, etc.)
Your style manual or referencing guide will tell you what these should be.
Write it up
Use your style manual or referencing guide to arrange the referencing details in the correct order (i.e. author/s year title etc.)
Now include the correct punctuation - exactly as it appears in the examples in the style manual or guide.
Beware of copy & paste Never blindly trust the Cite links you find on websites or even library databases, because there are many different referencing styles, and even different versions of the same style. When you copy and paste a reference, you will probably have to edit it to match the referencing style used by your School - so check each reference carefully.
Consistency is key
Make sure all of your references follow the same style. A reference list that is a jumble of different styles is very noticeable to the person who is marking your paper.
