Copy both databases to one Excel worksheet preferably in the same column(s).

Then the massaging starts.

What do you want to do with duplicates if/when found?

Keep one of each and delete the extras?
Use Advanced filter and check "unique records" and "copy to another place"
See Debra Dalgleish's site for more on this.

Tag them so you know which are duplicates and hide them?
See Chip Pearson's site for tagging and highlighting duplicates

Any ideas?
