I like this pre-pub, which shows vocabulary usage for each Bible book.

Is there a way to do this kind of search in Logos? Say, a frequency list of words in Mark's Gospel?
Would not the concordance tool give this for Mark or perhaps I am misunderstanding your question?!
Try using the Concordance Tool - see https://support.logos.com/hc/en-us/articles/360015929112-Concordance-Tool for pointers
