How do I exclude sources in a Turnitin originality report?
Excluding Sources in Turnitin
Removing a source from an Originality Report will "recalculate" the similarity index without consideration to the removed source in question. This feature is used for many reasons, but is often used when a paper has been submitted twice or more to Turnitin, and the Originality Report is reporting a high match (e.g. 100%) to a previous submission. Removing a source from an Originality Report may provide a more clear similarity index (percentage).
