The fonts are very close to Librum-Book and Librum-Italic, with the same OpenType features. The glyphs are modified a bit to make them a little more elegant, but that’s not very noticeable.

Mainly, the letterspacing and kerning is tighter and more carefully fit to large point sizes. 

As for classification, I like oldstyle, venetian, geralde, english oldstyle. There’s discrete modulation, slanted crossbars, full brackets serifs of medium thickness and sharp cut ends.
