A citation is the way you tell your readers that certain material in your work came from another source and gives your readers the information necessary to find that source again. Citations include:
Information about the Author(s) or Editor(s).
The Title of the work
The Publisher
The Date published
The Page Numbers of the material you are referencing
Why should I cite sources?
Giving credit to the original author by citing sources is the only way to use other people's work without plagiarizing. But there are a number of other reasons to cite sources:
Citations are extremely helpful to anyone who wants to find out more about your ideas and where they came from.
Not all sources are good or right for your project -- your own ideas may often be more accurate or interesting than those of your sources. Proper citation will keep you from taking the rap for someone else's bad ideas.
Citing sources shows the amount of research you've done.
Citing sources strengthens your work by lending outside support to your ideas.
Doesn't citing sources make my work seem less original?
Not at all. Citing sources actually helps your reader distinguish your ideas from those of your sources. This will emphasize the originality of your own work. It also gives you greater credibility because you are demonstrating your knowledge on the subject and your understanding of the work that's already been done by others on the subject.
Whenever you borrow words or ideas from another source, you need to acknowledge that source. The following situations almost always require a citation:
Whenever you use quotes
Whenever you paraphrase
Whenever you use an idea that someone else has already expressed
Whenever you make specific reference to the work of another
Whenever someone else's work has been critical in developing your own ideas
