Some courses have the option to turn in assignments through a plagiarism checker like you are referring to in Blackboard called SafeAssign. You can ask your professor via email if you are unsure whether or not this service is available in your course. This varies according to the course requirements. There is nothing in the library itself that will check your paper for plagiarism.
