Okay, this might be a little esoteric, but I was actually wanting to do this the other day within the sheet music catalog.

It would be interesting to add the period to each composer (Renaissance, Baroque, Classical, Romantic), so that you could search by period, or, for example, list all compositions for a specific instrument by period.

Anyway, maybe that's a strange request, but I thought it would be useful.
