Hello, I have another question too. I have a bunch of Adobe Caslon Pro font files in OTF format. In addition to Normal, Italic, Bold, and BoldItalic versions, there are Semibold and SemiboldItalic. How to make use of two latter in XeTeX (e.g, for section captions)? Now I simply have \definetypeface [myface][rm][Xserif] [Adobe Caslon Pro] \setupbodyfont [myface, 11pt] Best, Vyatcheslav
