User:Polygnotus/DuplicateReferences
This script detects and displays references with duplicate URLs. It also calculates how similar the visible text of those references is as a percentage. Hovering over and clicking on the reference number highlights it and its duplicates. You can add a {{Duplicate citations}} template to the page by clicking the link next to the References section header.
