Creative ways to use the Concordance Tool

Francis

I was wondering what ideas that community of users has come up with to take advantage of the Concordance Tool functionality. I thought I would start this thread to allow those who so desire to share some of the ideas they came up with. 

One of mine: I used the CT to find out what are the sources ancient authors used the most. This works in resources that cross-reference such sources. I have had success in doing this in Loeb perseus volumes (e.g., not surprisingly, Plutarch's leading source for Agesilaus is Xenophon). I looked also in Josephus to find out not only his sources but where other Jewish works (other than the Bible) are referenced and how often.
