RefWorks is a web based citation management tool that you can access from any internet connected computer.
If you fail to properly cite or give attribution to the original source material, you are presenting yourself as the original author and your work as the original source of the words or ideas you obtained elsewhere. You are taking credit for someone else's work, which is considered plagiarism and may result in copyright infringement.
If you make a mistake when quoting, paraphrasing, or interpreting the original source material, providing a reference to the original content allows anyone, whether it is you or your audience, to refer back to and understand the source material as originally intended.
Rather than explain the history of a topic, you may decide to pull key concepts from other works and refer only to those concepts in your own writing. You may do this because of space constraints or because you expect your readers to already have an understanding of the topic being discussed. However, not everyone who sees your work will be familiar with the topic. Including the citation to the original source where a concept or text was taken from, allows readers to gain a better understanding of the background or basis of your writing, so that they can then understand your arguments.
It may turn out that the original source you used contained typographical or factual errors. If you provide the citation to the original source material, you can show that the resulting error in your writing was due to errors in the original source.
Online tools, such as search engines and online databases, make it easier to search for resources that cite or are cited by others. Including proper citations creates a network of resources that is beneficial to you, authors of works you refer to, and people conducting research after you.
