Academic Integrity - Referencing, Citation & Avoiding Plagiarism: Avoiding plagiarism

This guide explains what referencing and citation is and how to use the APA, Chicago, Harvard, MLA and Vancouver Styles. It includes links to each style guide.

What is plagiarism and how do I avoid it?

Plagiarism

Plagiarism is the inclusion, in any form of assessment, of material without due acknowledgement of its original source. Plagiarism is a form of academic dishonesty and may include, but is not limited to, the following:

  • Presenting in your own name, work authored by a third party, such as other students, friends or family (with or without permission), or work purchased through internet services.  The original source may be in written form or in any other media (for example, audio or video);
  • Presenting ideas, theories, concepts, methodologies or data from the work of another without due acknowledgement;
  • Presenting text, digital work (e.g. computer code or programs), music, video recordings or images copied with only minor changes from sources such as the internet, books, journals or any other media, without due acknowledgement;
  • Paraphrasing (i.e., putting a passage or idea from another source into your own words), without due acknowledgement of the source;
  • Failing to include appropriate citation of all original sources;
  • Representing collaborative work as solely your own;
  • Presenting work for an assignment which has also been submitted (in part or whole) for another assignment at UCD or another institution (i.e. self-plagiarism).

Intentional versus Unintentional Plagiarism

Plagiarism can be either intentional (deliberate) or unintentional (mistaken). In both instances it is a serious academic offence and may be subject to University disciplinary procedures.

Definition from University College Dublin's Student Plagiarism Policy, which can be accessed here.

 

Important Information: Poor paraphrasing, where source material is copied with only minor changes, even if citation is included, still constitutes plagiarism." See our section, Paraphrasing Explained to learn how to paraphrase correctly.

Acknowledge all sources – if using information from others, indicate where it came from in your text and reference list using a citation style.

Record where all quotes or new ideas come from – when making notes in preparation for assignments.

Paraphrase correctly – express the information of others in your own words, along with an in-text citation and reference.

Quote correctly – when directly quoting from a text make sure you include the appropriate quotation marks or indentation. Include a reference at the end of your text also (See your School’s Style Guide for details).

Find out the citation style for your school and familiarise yourself with it. Keep the style guide to hand when writing assignments so you can include in-text citations and references in the correct format.

Common knowledge is knowledge that is known and accepted as true by members of a discipline. Here are some examples of common knowledge:

  • Water freezes on 0 degrees Celsius.
  • Mary Robinson was the first female president of Ireland.
  • Berlin is the capital of Germany.

Information that needs to be cited includes research undertaken by others, statistics, and ideas, interpretations or analyses of primary research or the work of others. Specific dates, numbers, or facts the reader would not know unless s/he had done the research also need to be cited.

If you are unsure if something is common knowledge or not, it is best to simply cite it. 

Common Knowledge is further explained on the Purdue University's Writing Lab.

Directly quoting the text

When using the exact words of another person it is essential that you indicate this in your text. The correct way to do this is by including quotation marks and usually a page number (depending on your reference style).

Below is an example of how to quote in your text correctly.

Original piece

The following ORIGINAL text has been taken from the book The Google Story.

“Not since Gutenberg invented the modern printing press more than 500 years ago, making books and scientific tomes affordable and widely available to the masses, has any new invention empowered individuals, and transformed access to information, as profoundly as Google.”

From: Vise, David A. (2005) The Google Story. Macmillan: London


Example of correct quotation

Google has revolutionised the way people access information in today’s information technological society.

“Not since Gutenberg invented the modern printing press ... has any new invention empowered individuals, and transformed access to information, as profoundly as Google.” (Vise, 2005 p. 1)

Google’s easy to use search engine enables users to access information quickly and efficiently through various options, including Google Scholar and Google Book Search.

This is the correct way to use a direct quote because

  • the direct quote is in quotation marks
  • the page number has been included

 

When to use quotations

  • when the exact words are relevant to your argument
  • when something is expressed in a unique way
  • when rewriting would cause loss of impact

Quotations should be used sparingly and should not be the dominant feature of your essay. However, some short quotations can make a strong impact. When using someone’s words you must use quotation marks, and state precisely where the quotation comes from i.e. cite the author, date and page number at the end of the quotation.

How to use quotations

Place a short quotation into the text (fewer than 40 words) using double quotation marks. Longer quotations should begin on a new line, and be in a free-standing block of typewritten lines.

Place the passage you are using in quotation marks, and give the author/source of information. Within a quotation use three dots (…) to indicate omitted words.

Example using APA Style

He stated that Google has "empowered individuals and transformed access to information" (Vise, 2005 p. 1).

OR

Vise (2005) argues that Google has "empowered individuals and transformed access to information" ( p. 1).

Paraphrasing is writing the thoughts and ideas of others in your own words. All paraphrased information included in your work must be cited. An in-text citation must be included beside the paraphrased piece of text. You must include a full reference in your reference list to the source of your paraphrased information. Some citation styles also require a page number for the paraphrased information to be included as part of the in-text citation.

 

The following ORIGINAL text has been taken from the book The Google Story.

“Not since Gutenberg invented the modern printing press more than 500 years ago, making books and scientific tomes affordable and widely available to the masses, has any new invention empowered individuals, and transformed access to information, as profoundly as Google.”

Unacceptable paraphrasing of above text - plagiarism

The most important invention that has affected access to information since Gutenberg invented the modern printing press and made books affordable and widely available, is Google, an invention that has empowered individuals and transformed access to information around the world.

This passage is considered plagiarism because

  • The writer does not cite the author as the source of the ideas
  • The passage is too close to the original text
  • Only a few phrases or words have been changed

If one or more of the above criteria are included in any piece of work, it is considered plagiarism.

Acceptable paraphrasing of above text - not plagiarism

It has been stated that Google has revolutionised the information world by providing access to information through the internet. Vise notes that Google is the most radical information development since Gutenberg's invention of the printing press. (Vise, 2005, p.1)

This is acceptable paraphrasing because

  • The author of the text has been cited correctly
  • The writer has used their own words
  • The writer gives credit for the ideas in the passage

The Internet is a popular source of information for student papers. To avoid plagiarising these sources follow the same guidelines as print sources.

  • when referring to ideas or quotations from a website, you must cite that source in your text.
  • when copying visual information or graphics such as images or data charts from the Internet, the source of the visual information or graphic must be cited.
  • each reference style has particular rules about including URLs, website names and accessed date information, check with your school style to see what guidelines are given.

Examples

For example in the APA style the Author of the website should be cited in-text, and a full reference given at the end for the website including the URL.

In-text citation, APA Style:

Examples of plagiarism

Each of the anonymised and adapted cases of plagiarism on this page are outlined in order to help you recognize plagiarism in academic practice. All examples were referred to UCD's Student Discipline Procedure and received a sanction. Read through each of these examples and think about how the student may have avoided plagiarizing.

We have lots of resources on this guide to help you manage time, plan assignments, and cite and reference appropriately. UCD Writing Centre offer a free-of-charge service dedicated to supporting UCD students.

If you find yourself under pressure or stress to finish an assignment, ensure you contact your module coordinator to discuss your options around an extension or extenuating circumstances. You can also seek help from your student adviser who can facilitate communications and ways to solve problems. UCD has a student counselling service with superb in-person and online supports.


Types of Plagiairism Include:

  • Using thoughts and ideas from a piece of work without crediting the author in your references
  • Copying and pasting large sections of text from other sources into your work
  • Copying a diagram, image, graph or photo, without a reference to the source
  • Copying a chunk of text, changing the odd word or phrase with or without in-text citation or referencing
  • Re-submitting your own work in another assignment or module is Self-Plagiarism
  • Failing to use quotation marks (“”) when directly quoting another person’s words or work
  • Patchwork plagiarism, where text is copied from different sources and knitted together, without any acknowledgement
  • Using an assignment, project, essay or dissertation purchased online or from a person
  • Not acknowledging any collaborative or group work in your own piece of work

Undergraduate Module

An essay was submitted by a student who had already submitted the same essay for another module within their programme in the previous year. The examiner noted that the essay only partially addressed the topic of the given assignment. The student stated that they did not know anything about self-plagiarism and thought it would be acceptable to submit an essay again, because it was their own work. 

Note: Self-plagiarism occurs when a student submits their own work which has already received credit. It is important to be aware of the different types of plagiarism, as unintentional plagiarism can still result in a sanction. 

Undergraduate, Thesis Module

Examiners noted irregularities and unusual characteristics in a student's undergraduate thesis. Much of the content of the thesis did not relate to the research conducted by the student. Another person’s name was discovered to be associated with the file submitted by the student. The examiner was able to trace the source material to an “essay mill” type website. In this case, the student admitted that they had submitted a thesis which they had bought online from an ‘essay mill.’

Taught Masters, Thesis Module

A student was asked to prepare a presentation to summarise their thesis preparation. The work submitted contained no quotes, citations or references to academic works. In addition there were significant unacknowledged sections that were taken from another student's masters thesis which was found to be freely available online. 

The examples of plagiarism in this case include

  • several instances where the student quoted verbatim from a text that was not cited
  • multiple instances where the student quoted extensively (paragraphs at a time) from a masters’ thesis available online
  • verbatim quotation from numerous websites without citation or attribution
  • quotation from academic work without appropriate page number(s)

Taught Masters, Professional Learning Journal Module

A student was assigned a task to reflect on learning gained during four of the module’s classes. The student had to then produce a summary reflection essay exploring how this learning might be further applied to their own development and practice. The assignment required reflection on discussions that took place during classes, assigned readings and demonstration of connections made to other learning attained across the programme.  

In this case the student directly quoted from academic texts and used ideas without either quotation marks or citation. There were several examples where the student had quoted extensively from a journal article without appropriate acknowledgement.  In a number of instances, citations were used for ideas that did not correlate with the papers referenced in the assignment. 
 

The examples of plagiarism here were

  • misrepresentation of the work of academics whose work was cited
  • quotation from assigned readings without quotation marks or attribution (citation or references)
  • quotation without clear attribution or page number
  • quotation from other academic journals without attribution
