When you quote or paraphrase another person's idea in your research paper, presentation, or speech, you need to provide a proper citation for the source.
A citation is a reference to a source of information.
It should include enough identifying information so that a reader can locate a copy of the item. This information can include information like the title, author, journal title, and publication date. Knowing how to interpret citations that you find in indexes or bibliographies, in addition to citing sources for your own references, is an important skill you will use throughout your academic career.
Using someone else's ideas or language without giving them appropriate credit is called plagiarism. Plagiarizing someone else's work is academically dishonest, and a violation of the NSU honor code. Citation can seem stressful, but avoiding plagiarism is easy-- especially easier than dealing with punitive measures by an instructor, the University, or a publisher.
