Both Ouriginal and Turnitin use three types of sources:

• Work submitted by students.
  Documents that were previously submitted by students in Ephorus and SafeAssign have been imported into Ouriginal. These documents in Ouriginal have all been imported into Turnitin and are thereby also protected from plagiarism.
• Publications from scientific publishers.
• Web searches.
