Citing and Writing
Why cite your sources?
You must document the sources you used in order to give recognition to the original author. Whether paraphrasing or using direct quotes, ideas that are not your own must be cited.
How do I choose a style?
Your instructor will provide you with the preferred style for your course. They may also have specific formatting instructions. Remain consistent with style and formatting, and provide enough information for the reader to identify the work or cited material.
Confused by the different citation styles? This chart provides a side-by-side comparison of APA, MLA, and Chicago styles. It is available from the OWL at Purdue website. Librarians are available to help with citations and referencing, choose an option below to connect with a librarian.

About APA Style
The style manual from the American Psychological Association (APA manual) uses an author-date citation format. When citing sources in APA, regardless of the resource you are citing, you will likely need an author, date, title, source, and specific format information (such as a volume number, page numbers, a URL, publisher, etc.). The elements of the citation will depend on what you are citing (book, journal article, report, etc.) and the format (print, online).

Citation Management Tools
Managing citations and referencing sources is an important part of academic writing. Online citation management tools are available to help you create and manage citations. These tools allow you to access and manage your sources online in a single place, insert in-text citations, footnotes, and bibliographies into documents, share sources with others, import references from library databases and websites, organize and search saved citations, and more.
- Zotero - A free, open source tool to help you collect, organize, cite, and share research sources. Organize citations into folders, add tags, make notes, and automatically generate bibliographies in dozens of citation styles. Citations can easily be added by dragging and dropping PDFs. With the Chrome browser add-on, Zotero will automatically download citation information from compatible websites. A Word plugin is also available and once installed, the Zotero toolbar allows you to insert citations and generate bibliographies inside your document. Syncing across computers is also available, allowing you to have the same citations across devices.
- Mendeley - A free reference manager to help you organize and share your research. Available as an app or desktop version, allowing syncing between multiple computers. A Word plugin is available to add documents to bibliographies and add in-text citations. Excellent app for those working in groups. The ability to share documents allows groups to assign people with different aspects of the research, and then share their their cited articles through a shared folder. Free with up to 2GB of storage.
- Microsoft Word - Most word processing software includes citation management tools. In MS Word, go to the References tab, then click on Insert Citation, then click to Add a New Source. More information is here.
- EndNote Basic - Free web-based service used to store references and create bibliographies. Offers up to 2GB of storage.
- Library databases - Many library databases will have a “Cite” tool or “Citation” generator. Use this to generate a citation for the source. Review the citation according to a citation style guide to ensure accuracy.
- Unsure which is the best option for you? MIT and UVIC libraries have charts that compare the different features of EndNote, Mendeley, and Zotero.
Be sure to review any citations for accuracy. Spelling and syntax errors are common with computer-generated references. The Library will help you construct citations and review reference style guides. Staff may not be able to assist with citation management software.
Keep your personal privacy in mind when using these online tools. Citation management products store data on non-Canadian servers. Use of these reference services is voluntary. Your username, email address and citations may be stored in the US or another country. Your account information will be subject to the laws of the country where the information is stored.
Assistance with writing and study skills is available through the College's Learning and Success Centres located on all campuses. Learning Coordinators help students become effective independent learners through individual and small group academic assistance in Math, Sciences, English (reading and writing), and Study Skills.
Due to COVID-19, all Learning and Success Centre activities have been moved online. More information can be found on their website.
Academic Integrity and Plagiarism
"Academic integrity is a cornerstone in the development and acquisition of knowledge. It is founded on values of trust, fairness, respect, honesty and responsibility."
Plagiarism is in violation of the Academic Integrity policy. According to the Policy, plagiarism includes but is not limited to, when a student:
- submits or presents work of another person, in whole or part, as that of the student's own work;
- fails to provide adequate attribution (author/creator must be acknowledged in the text, in footnotes, in endnotes, or in another accepted form of academic citation) to an author or creator whose work is incorporated into the student’s work, including another person's words, ideas, or entire works;
- paraphrases material from a source without sufficient acknowledgement;
- does not ensure the work is the student's own after the student has sought assistance from a tutor or other scholastic aids.
In fact, there are many "shades" of plagiarism. Students may unwittingly (or wittingly!) commit plagiarism. The Library and the Learning and Success Centres are available to help you plan your assignments and assist with research so you can avoid plagiarism.
