Sorting the lists in the same way would simplify a manual check.

I would however get them both into tables in Excel and then use a Find
Duplicates query there to identify the duplicates.

You could also make use of the example 4 in the article "Finding and
replacing characters using wildcards" at:

http://www.word.mvps.org/FAQs/General/UsingWildcards.htm

Or you could create a macro that iterated through the records in one list
and compare each one with the records in the other list.
