Query: Good production, lacks etymology, academic rigor

There are some good words on the five CDs (a bargain), although it takes some initial breaking in to not be annoyed by the flamboyant speakers. What the CD completely lacks, as it was purported to have, is a discussion of the roots of words. This discussion was rarely had, and in one case (to my knowledge), was incorrect. Not for any serious Classics student hoping to reconnect with contemporary roots.
