You've found all these great sources, now what?
Whether you use note cards, color-coded binders, stacks of photocopies, or bookmarks made from licorice whips (please don't), having a strategy to stay on top of your research will help your project stay on track.
The Libraries offer several aids for managing your references, be they a few or a few hundred.
Citation Managers allow you to create a personal database of references you have collected, to orgranize and annotate those references, and then to generate reference lists and bibliographies, footnotes, and endnotes in specific citation formats.
