Why reference
Referencing is an essential part of academic writing. As a student or researcher, you are part of a scholarly community, and it’s important to articulate which ideas in your work belong to you and which belong to researchers that have gone before you.
Clearly acknowledging where ideas come from establishes credibility.
- If you are writing an assessment, your tutors will be able to see some of the research you have undertaken and how it’s contributed to your thinking and understanding of a topic.
- If you are writing a research paper, it quickly helps the reader to find your sources and evaluate for themselves the validity of the research you’re using and whether you’ve used it appropriately.
Accurate referencing also ensures academic integrity. By providing references consistently in your writing, you:
- are being honest and transparent
- avoid academic dishonesty, which can result in penalties.

When to reference
You should provide source information:
- when you quote (use words verbatim), paraphrase, or summarise (write in your own words) another person’s ideas or arguments
- when you use or interpret facts, information, or statistics (including diagrams, datasets, images, video, or audio) in your work or to support your claims
- when you interpret or draw original conclusions from well-known facts
- when an idea or fact is too subject-specific for a general audience
You don’t need to provide source information:
- for information that is common knowledge (i.e. information that people agree about and which is available in a range of reliable sources)
- when you are presenting your own ideas or opinions, unless they have been published elsewhere.
The safest rule is: when in doubt, provide a reference!
Tip: Check with the style you’re using how to pinpoint the exact part of a particular source you’re referencing. It’s important to be clear whether you’re referring to a source in its entirety or a particular page, paragraph, section, table etc.
How to reference
Referencing generally has two key elements:
- an in-text marker (often referred to as an in-text citation) attributing a particular quotation, paraphrase or idea to someone else
- a complete reference list giving the full details of all sources referenced in the document including:
- Author: Who created the work?
- Date: When was the work published?
- Title: What is the work called?
- Retrieval information: Where can I find the work?
The way you are required to write the in-text citation and the reference list is determined by the reference system and style you use.
Reference systems and styles
There are two common systems for referencing:
Note systems involve the use of sequential numbers as in-text markers that refer to either:
- footnotes included at the end of each page
- endnotes provided on a separate page at the end of a paper (not to be confused with EndNote, a reference management system).
Styles that use note systems: Vancouver, Royal Society of Chemistry, and Institute of Electrical and Electronics Engineers (IEEE).
Parenthetical systems involve the use of a partial reference in parenthesis as in-text markers (such as the author-date). The complete reference is then included in a bibliography or reference list on the last page of the document.
Styles that use parenthetical systems: American Psychological Association (APA), Harvard, and Modern Language Association (MLA).
Choose a system or style
For assignments, check with your lecturer if your faculty has a preferred style.
If you are a researcher, you may need to follow the style of the publication you are writing for, or select a style more commonly used in your field.
Be consistent
Always be consistent when using a particular referencing system and citation style, as you can't mix formats within the same document.
Where to learn more about a style
Reference list or bibliography
For assignments, check your assignment outline or ask your lecturer if they expect a reference list or a bibliography, otherwise check with the publications you are writing for:
- A reference list contains only the sources you refer to in your writing.
- A bibliography includes everything you have read on a particular topic, whether you refer to it in your writing or not.
Referencing Indigenous knowledge
For guidance about citing Indigenous knowledge, consult the Indigenous Referencing Guidance for Indigenous Knowledges.
The publication first helps you to consider if you have chosen appropriate sources, including Indigenous authored and / or those preferencing first-person experiences. It then provides advice about how to incorporate the author’s Nation, Country or Language Group.

Reference management tools
We recommend the use of reference management tools when you are working with large numbers of references and associated files. Find out more about their recommended use and limitations.
