I was going to reply, you don't seem to be seeing the font that's on the page. The font they're using is a renamed copy of Baskerville eText, and it doesn't have an 'st' ligature. It does have 'ff' and 'fi', you can see a sample here: http://myfonts.us/td-JZwQMI http://myfonts.us/td-JZwQMI The css for the page enables ligatures however, and falls back to the browser's own serif; so you were probably seeing the ligatures from your own default font. I'm guessing Adobe Caslon Pro, because it's widely available and has a very distinct loop ligature for 'st'. http://myfonts.us/td-C4VrUX http://myfonts.us/td-C4VrUX
