80. Designing Type by Karen Cheng.
So, I've been working on a personal typography project - a hearty, sans serif face for personal use - and discovered Designing Type by Karen Cheng. This book is a great reference for such an undertaking, going through an alphabet character by character while focusing on balancing the optical issues of shape, form and consistency within a typeface. Here are a few preview pics (1 , 2 , 3 , 4 , 5) via youworkforthem.
