You can try this macro (saved as NWP macro with .nwm extension) on a copy of your file of citations:

Edit:Sort Paragraphs:Ascending (A-Z)
#Find and replace all instances of sorted duplicate paragraphs with one instance of the same.
Find and Replace '^(.+\n)\1+', '\1', ‘Ea'

It will sort the paragraphs so that all duplicates are brought together, and then replace all duplicates with one instance of the same.
