I found a scan error in one of my resources: "modem" instead of "modern". I figured this was a common error so I searched my library for "modem" so I could report more typos. Then I got discouraged:

This is a theological library, so the probability is that most of them are errors. Maybe someday I'll get them all reported. 
I suggest Logos build a list of these common scan errors (especially words with "rn") and search for them to help auto-proofread.
