Tim Allison commented on PDFBOX-3058:
-------------------------------------

Will do.  On the two extra columns...

One is the sum of non-unique (tokens not types) "common English words >= four 
letters".

What is the other extra column?

For "common English" words, what would you think of using [norvig's 
list|http://norvig.com/ngrams/count_1w.txt] from rank 20, say, to 100,000?
