I have been asked a question about how to reference work. A useful style is the Modern Languages Association of America (MLA) at http://webster.commnet.edu/mla/index.shtml
Clicking on "Citing Sources" will bring up a sub-menu of the many types of documents one typically encounters. For each type of document, there is an example of the citation.
As well, your software may refer to citations differently. For example, WordPerfect calls citations end notes.
