Often referred to as "The Typographer's Bible," Chapter 6 of The Elements of Typographic Style covers Choosing and Combining Type. Bringhurst reminds us to "Choose faces that will survive, and if possible prosper, in the final [screen] conditions" and to choose faces that suit the task as well as the subject. He tells us to "start with a single typographic family," but when the time comes to combine fonts, "balance the type optically more than mathematically."
