ci·tá·tion: noun: A quoting
of an authoritative source for substantiation. --The American Heritage® Dictionary
of the English Language: Fourth Edition. 2000.
A citation is a brief description of one specific
information source, usually appearing in a bibliography,
list of references, or a database. It includes
enough information to permit the reader to find
the source and may appear in a number of variant
formats, e.g. American Psychological Association
(APA), Modern Language Association (MLA), Council
of Biology Editors (CBE), or Chicago Style.
A citation is made of parts, each part indicating
specific information about the source. You can
usually tell what type of source is being described
by looking carefully at the citation. The citation
below (in APA style) refers to an article found
in a journal called Climatic Change.
