If your instructor wants you to submit your paper to Turnitin, they will set up a Blackboard assignment in your class that you will see when you login to Blackboard. Submitting your paper through Blackboard to Turnitin requires no further set up or login than your Blackboard one.
If your instructor does not use Turnitin, you can ask the library to run it through Turnitin for you. You will receive a PDF of the originality report. Your instructor will also receive a copy of the originality report.
