Citation Styles are a set of rules or standards established by a specific society, association or publisher for documenting various sources of information. These sources of information may include journal articles, books, thesis, online sources, unpublished manuscripts, magazines, grey literature, etc. Detailed descriptions of the citation styles (often known as Style Manuals or Publication Manuals) can be found on the websites of those societies, associations or publishers who set and maintain the citation standards. Styles may be revised from time to time in which case new or up-dated Manuals are released. It is a good practice to consult the original Publication Manuals for updates.
DEVS 240 requires that you use the American Sociological Association (ASA) citation style. You can find information and instructions on how to cite your sources using this style here:
