All sources should be cited in a bibliography or reference list and in the text or footnotes of a research paper.
Citations give credit to the the author as well as enable other researchers (or your instructor) to locate the cited item.
In addition to this guide, Binghamton University Libraries also offers two interactive tutorials on the Online Tutorials page: Tutorial 2: Avoiding Issues of Academic Dishonesty and Tutorial 6: Citing your Sources.
Refworks allows you to import and arrange citations, then use those citations to format your in-text citations or footnotes and bibliography in a wide variety of styles, including APA, MLA and Chicago.
Refworks is available for members of the Binghamton University community through a subscription from Binghamton University Libraries.
In addition to Refworks, there are a variety of other reference management tools available.
