To properly recognize the work of others whether it is a book, article, or image, consistent citing of references is needed. If you write a paper or a blog entry, always cite your source. Paraphrasing of a source must always be cited. Direct quotes must always be cited. Only your own work does not require citation. However, as an author you should expect that your work will be cited.
Citation styles are in the hundreds. Each journal has its own style guide. Societies like the American Physcological Society have their own, highly detailed guide which is used by many citation managment softwares like EndNote and RefWorks.
The preferred citation style for this class is the one used for the journals:
