Greek fonts to match the URW Bookman set (which are distributed with Kerkis). The Kerkis font set some support for mathematics as well as other glyphs missing from the base URW Bookman fonts. Macros are provided to use the fonts in OT1, T1 (only NG/ng glyphs missing) and LGR encodings; small caps and old-style number glyphs are also available.

The philosophy, and the design process, of the Kerkis fonts is discussed in a paper in TUGboat 23(3/4), 2002. The author is Antonis Tsolomitis.
