Libre Baskerville
Sphinx of black quartz, judge my vow
ITC's 1978 redrawing, which is what most people have actually set when they have set Baskerville.
A larger x-height and a tighter fit than the eighteenth-century original, which matters because it is the version body text was laid out in.
One entry, because one is the honest answer. A face is listed here only if the substitution would survive a designer looking at both.
