Citations tell where your research information came from. It includes information such as the title of a book or web site, the author, the date or publication, the publisher, and so forth. This information is arranged in a standard format which is determined by the Modern Language Association (MLA), an international group.
There are at least two reasons for citing your sources. First, you are providing information which will allow your audience to go back and re-read the same information that you read. Second, you are being honest and acknowledging that the ideas are someone else's and not yours.
Many online programs can help you to create citations without having to remember a lot of rules. Bibme ( is one such program. By entering information about a book or electronic resource and then clicking the submit button, you can create a perfect citation every time.
