How-to guides and videos on writing, research and citation
Check out our Citation Guide that can help you cite it right! It also contains a list of suggested Citation Management software.
Citation is never optional! Your reader needs to know the source of your ideas, and you need to provide credit to those you have read. Remember: you need to cite all sources in-text as well as in a works cited or bibliography list. Every citation style is different (be sure you know your professor's expectations) but all share the same function: they provide support for your arguments, because Information has Value!

Why We Cite |
Citation: A (very) Brief Introduction |
![]() |
To attribute words and ideas to their original source – simply giving credit where credit is due
To provide your readers with a kind of “map” of what you have been reading that will help your readers understand what has influenced your thinking
To add weight and credibility to your paper and demonstrate that you are engaged in the relevant research material
To provide an easy way for your readers to get access to the source material
To situate yourself in an academic community with shared conventions
To avoid plagiarism.
your papers or that influence your ideas.
You don’t need to cite what would be considered common knowledge, such as facts, events, concepts, etc. that are widely known and accepted as true. In other words, you don’t cite information you can reasonably expect other people to know.
For example it is widely know that there are bilingual (French and English) speakers in Montreal. So if you wrote, “there is a bilingual population in Montreal”, you don’t need to cite this because it’s an accepted fact, or common knowledge.
BUT, the specific number of bilingual speakers or percentages of where they live is not common knowledge. So you if you wrote, “70% of bilingual speakers live in the downtown core of Montreal,” you would cite your source.
So: how can you tell what’s your own idea and what came from one of your sources? The best way to avoid this dilemma is to use good note-taking techniques. Make sure when you are going through your notes, you have indicators of which ideas are your own and which ideas or quotes are from a source. Remember to always keep track of a source’s Author, Title and Publication information (as well as the page number).
If you are in doubt whether something is common knowledge or not, cite!
Better safe than sorry.
Citation Styles differ depending on your field of study. Even in the Humanities, you might find three different professors prefer three different citation styles. Each is simple if you follow the templates: check out the following guides on each style (if you're not sure which style to use, check your syllabus or ask your professor) and seek out examples based on the type of resource you're using (journal, website, book, etc).
