TYPOGRAPHY SHELF #1
My personal favorites are starred.

☆ Wolfgang Weingart, My Way to Typography
☆ Simon Loxley, Type: The Secret History of Letters
☆ Robert Bringhurst, The Elements of Typographic Style

Weingart’s book is a lot about process and has many sketchbook drawings, items of inspiration and experimental graphic compositions. Type: The Secret History of Letters is like “Behind the Music” for pre-digital typography. It has great stories about pivotal people in type design, their lives and legacies. Bringhurst’s The Elements of Typographic Style is the bible of typesetting. I think every typographer should curl up with this book and read it like a novel. After, keep it nearby for reference.
