There are numerous concordances that list all of the words, and their frequency of use within each of Shakespeare's plays. However, I am interested in the presence and frequency of use of words across those plays.
For example, I would like to compare the frequency of the term beauty in "Hamlet" with its use in "The Tempest."
While this can be done manually by looking up the instance in the separate concordances of each of the plays, is there a project or program that does this for all of the plays (or some subset of them)?
