More About the Bookerly Font
Caecilia has some of the same characteristics of the slab serif Bookerly, but the new font is far more graceful and even on the type line. The font it reminds me of the most, and one I've used in the books I design, is Adobe's Chaparral, designed by Carol Twombly and released in 2000.
