There are a few instances in which Latin (and perhaps French) titles have been given full capitalization or no capitalization in some versions of the Ms. text, e.g.,
Fol. | TC | TCN | TL ---- | ---- | ---- | ---- 170v | Reru{m} scoticarum historia | Reru{m} Scoticarum Historia | Rerum Scoticarum Historia 170v | de stirpium historia | de stirpium historia | De stirpium historia
It's a rare occurrence, and 1r looks pretty good, but it's worth a quick once over.
