How to avoid plagiarism

Plagiarism means using someone else’s words or ideas without properly crediting the original author. Sometimes plagiarism involves deliberately stealing someone’s work, but often it happens accidentally, through carelessness or forgetfulness.

When you write an academic paper, you build upon the work of others and use various sources for information and evidence. To avoid plagiarism, you need to correctly incorporate these sources into your text.

Follow these four steps to ensure your paper is free from plagiarism:

1. Keep track of the sources you consult in your research.
2. Paraphrase or quote from your sources (and add your own ideas).
3. Credit the original author in an in-text citation and reference list.
4. Use a plagiarism checker before you submit.

Plagiarism can have serious consequences, so make sure to follow these steps for every paper you write.

Step 1: Keep track of your sources

While you are doing research and taking notes for your paper, make sure to record the source of each piece of information. One way that students commit plagiarism is by simply forgetting where an idea came from and unintentionally presenting it as their own.

You can easily avoid this pitfall by keeping your notes organized and compiling a list of citations as you go. Keep track of every source you consult – that includes not only books and journal articles, but also things like websites, magazine articles, and videos.

Then you can easily go back and check where you found a phrase, fact, or idea that you want to use in your paper.

Step 2: Quote and paraphrase

While writing your paper, if you want to share an idea or a piece of information from a source, you must either paraphrase or quote the original text.

Quoting

Quoting means copying a piece of text word-for-word. The copied text must be introduced in your own words, enclosed in quotation marks, and correctly attributed to the original author:

According to Cronon, the concept of wilderness is a cultural invention: “Far from being the one place on earth that stands apart from humanity, it is quite profoundly a human creation – indeed, the creation of very particular human cultures at very particular moments in human history” (1995, p. 69).

Paraphrasing

Paraphrasing means using your own words to explain something from a source. It allows you to give only the most important information from a passage.

To avoid plagiarism when paraphrasing, you need to make sure that your text isn’t too similar to the original.

Paraphrasing vs. quoting

In general, paraphrasing is better than quoting, especially for longer passages. It shows that you have fully understood the meaning of the original text and ensures that your own voice is dominant in your paper.

Quotes are appropriate when:

• You are using an exact definition introduced by the original author
• It is impossible for you to rephrase the original text without losing its meaning
• You want to maintain the authority and style of the author’s words

Whether you paraphrase or quote, always build on your sources by adding your own ideas, interpretations, and arguments.

Step 3: Cite the original source

Every time you quote or paraphrase, you must include an in-text citation (or footnote citation) that identifies the original author. It often also includes the publication year and a page number.

Each in-text citation must correspond to a full reference in the reference list or bibliography at the end of your paper. This details exactly where the information came from, allowing your readers to locate the source for themselves.

There are many different citation styles, and each one has its own rules for citing. Some of the most common include APA, MLA and Chicago Style. The most important thing is to apply one style consistently throughout the text.

Step 4: Use a plagiarism checker

Most universities use plagiarism checkers to detect plagiarism in student papers. This technology scans your document, compares it to a huge database of publications and websites, and highlights passages that are overly like other texts.

You can use a plagiarism checker yourself before submitting your paper. This allows you to identify any parts where you’ve forgotten a citation, left out quotation marks, or included a paraphrase that’s too close to the original text. Then you can follow the steps above to easily fix any instances of potential plagiarism.
