For Browse by Period and for the list of Manuscripts under a particular content/poem, the order of display for the manuscripts seems random – e.g. a Folger Library item first, then Beinecke, then back to a Folger ms. It would seem that the display should be alphabetical by archive, at least.
They should have a sort order, but we will need to confirm with the team what that should be. I'd be inclined to say that the manuscripts ought to be sorted by date in both "Browse by Period" and the "Manuscripts" tab, since that would make the most sense in both contexts. (The former since you're browsing chronologically; the latter since it would give a better sense of the chain of adaptations.)
