A word on citation software
General introduction to citation practices
Part II. Source Citation

Software companies offer a variety of programs that format bibliographical information according to a specific citation style, including the styles covered in the following chapters. Such a program may save time, but it is not a substitute for knowing the underlying principles of the style. Morever, citation and bibliographic management software varies widely in quality and might not reflect the small changes in citation styles that occur over time (for example, the addition of different electronic sources). If you use such software, you should always review the resulting citations for accuracy and completeness.
