Simply put, RefWorks is a citation manager. You can export article information from the various databases -- EBSCO Academic Search Premier, ProQuest Nursing and Allied Health, OVID ADU Journals, Science Direct etc. to RefWorks. You can then alphabetize and create a "bibliography" in any style format you wish -- i.e. APA, MLA, Chicago Style etc.
This is useful if you are compiling many article citations. RefWorks will allow any type of citation -- books, websites, etc, but journal articles are very popular here at ADU.
