The Book on the Bookshelf is a book about books... and shelving. If that doesn't catch your attention, then there's no hope. I've lost you already. It's a study of part of our relationship with books, the ways we created, studied, shared, and stored them. Henry Petroski touches on developments in bookbinding, the evolution of outward-facing spines, and the history chained books, among other things.
I love the research that Petroski did. In many of the chapters scrutinizes old photographs, architecture, and especially the illustrations that can be found in old books---Renaissance scholars in their studies, Medieval monks in their libraries, etc.. How big are the books? How are they bound? How are they physically organized? How do they lay? A book is both a container of information and itself a piece of historical evidence. Pretty cool.
