Once upon a time, I had a fancy to hold aside the hyphenated words and do a mini-lesson on them – there are dozens and dozens, and I believe now that the most important thing is to get the concordance functional!

Update 2015.07.10: the concordance is functional, I’m publishing conclusions on my main topics, and I had time to run a graph of hyphens!

Update 2017.09.27: I’m so pleased to say we now have a Hyphen Mini-Concordance and all of the words therein have been checked against the OED to see what those venerable editors think of the hyphen.
