I've found a useful infograph about Type Faces. Cliff Kuang of Factodesign.com created the easy to understand infrograph. Fonts are an important part of the Jaffe Center, and we contain many books about fonts, how to use them, how to make them, or artists' books that play with fonts. At the Center, we use a lot of fonts that are created by Eric Gill, such as Gill Sans and Perpetua, which are clear, balanced, and modern.
A favorite artists' book of mine is Eclectic Geometric, or Lunch with Nicolete by Russell Maret. The portfolio book contains 26 prints of the 26 letters rendered with a compass and straightedge. The designs of the letters are beautiful and Maret has drawn the circles that have influenced the design of the letters. To read more on the book, check out Judith Klau's review here.
