Cite Your Sources Using a Standard Format or Style
Give credit where credit is due; cite your sources.
Citing or documenting the sources used in your research serves two purposes, it gives proper credit to the authors of the materials used, and it allows those who are reading your work to learn more by reading the sources that you have listed as references. Knowingly representing the work of others as your own is plagiarism. (For details, see Recognizing and Avoiding Plagiarism).
Available online: Duke University's online guide to citation styles using APA, MLA, Chicago, Turabian, and CSE.

You can also use EndNote, Zotero, and Mendeley to format citations. EndNote is available for purchase at the Cornell Store and to faculty, students, and staff in the College of Agriculture and Life Sciences. Zotero and Mendeley are free in the basic versions.
