A level unseens vocab learning tool

Atriades has noted a vocab learning tool on the Perseus site, which might go some way to helping with the compilation of a list as requested in yesterday's post.

Perseus can show all the words used in a particular work e.g. the Metamorphoses, or those that occur most frequently, whether the top 90%, 80%, down to 10%.

Apparently it's a slightly blunt instrument, confusing bellus and bellum, for instance, but it must be useful.
