Writers must be credited for their work and their writing.
Not to do so is to plagiarize.
Plagiarism is defined as intentionally or unintentionally using the ideas, language, or work of another without acknowledgement that such material is not one's own.
Whenever you quote, paraphrase, summarize, or otherwise refer to the work of another, you are required to cite its source. In research papers, any source information that you provide in an in-text citation must correspond to a source in your Works Cited page.
There are several common systems in use. At Otis College, the most common style is MLA (which is short for Modern Language Association), but you may come across others. There are style manuals for each style that you can use.
Follow your instructor's guidelines. Be consistent with whatever citation format you choose to use.

This citation guide is based on the MLA Handbook for Writers of Research Papers (8th ed.). The contents are accurate to the best of our knowledge.
Some examples illustrate Seneca Libraries' recommendations and should be viewed as modifications to the official MLA guidelines.
MLA style was created by the Modern Language Association of America. It is a set of rules for publications, including research papers.
There are two parts to MLA: In-text citations and the Works Cited list.
In MLA, you must "cite" sources that you have paraphrased, quoted or otherwise used to write your research paper. Cite your sources in two places:
Always give credit where credit is due.
Even if the source is in the public domain. Even when using the source is covered under fair use. Even if the material is released under a Creative Commons license that does not require attribution. Even when the source comes from social media, such as a Facebook or Tumblr post.
For more information, check our the Copyright and Fair Use guide.
Always check over auto-generated citations! Sometimes they make odd mistakes or capitalize all of the words. For instance, this auto-generated citation has parsed the author's name incorrectly.
