Bibliography
A list of sources used in preparing a work
Citation
A short, formal indication of the source of information or quoted material.

Information that is readily available from a number of sources or so well-known that its sources do not have to be cited. The fact that carrots are a source of Vitamin A is common knowledge, and you could include this information in your work without attributing it to a source. However, any information regarding the effects of Vitamin A on the human body are likely to be the products of original research and would have to be cited.
Copyright
A law protecting the intellectual property of individuals, giving them exclusive rights over the distribution and reproduction of that material.
Endnotes
Notes at the end of a paper acknowledging sources and providing additional references or information.
Facts
Knowledge or information based on real, observable occurrences. Just because something is a fact does not mean it is not the result of original thought, analysis, or research. Facts can be considered intellectual property as well. If you discover a fact that is not widely known nor readily found in several other places, you should cite the source.
Fair Use
The guidelines for deciding whether the use of a source is permissible or constitutes a copyright infringement.
Footnotes
Notes at the bottom of a paper acknowledging sources or providing additional references or information.
Intellectual Property
A product of the intellect, such as an expressed idea or concept, that has commercial value.
Original
Not derived from anything else, new and unique
Markedly departing from previous practice
The first, preceding all others in time
The source from which copies are made
Paraphrase
A restatement of a text or passage in other words. It is extremely important to note that changing a few words from an original source does NOT qualify as paraphrasing. A paraphrase must make significant changes in the style and voice of the original while retaining the essential ideas. If you change the ideas, then you are not paraphrasing -- you are misrepresenting the ideas of the original, which could lead to serious trouble.
Plagiarism
The reproduction or appropriation of someone else's work without proper attribution; passing off as one's own the work of someone else
Public Domain
The absence of copyright protection; belonging to the public so that anyone may copy or borrow from it.
Quotation
Using words from another source.
Self-plagiarism
Copying material you have previously produced and passing it off as a new production. This can potentially violate copyright protection if the work has been published and is banned by most academic policies.
