Recently I've been using a lot Junicode. It's an open source font based on scans of George Hickes, "Linguarum vett. septentrionalium thesaurus grammatico-criticus et archaeologicus" (Oxford: Sheldonian Theatre, 1703–5). Basically it's a humanist font, in the style of John Fell's Pica Roman.
I made a few modifications in FontForge for e-ink:
- Oldstyle numbers are now the default figures
- Regular and italic style have been embolded by +25
I also disabled the Qu ligature (imho too fancy for modern literature).
