Are you working on a paper for class, or looking ahead to final papers in your courses? If so, you may want to enlist the help of Writing Tutorial Services. WTS is available free of charge to students, and provides both hour-long consultations by appointment in their Ballantine office and half-hour help sessions in a walk-in atmosphere in Academic Support Centers on campus.
You can find more info and see how to make appointments on the WTS website. In addition, there are several pamphlets on writing issues like plagarism, creating an effective thesis statement, and using evidence and sources.
