Removing a source from an originality report will 'recalculate' the similarity index without consideration to the removed source in question. This feature is often used when a paper has been submitted twice or more to Turnitin, and the originality report is reporting a high match (eg 100%) to a previous submission. Removing a source from an originality report may provide a more clear similarity index (percentage).

  2. Click the View all submissions button

  3. Click on the Percentage to load the Turnitin Document Viewer
