Resumo:

We are so used to leafing through a book in the course of reading a text that we are hardly aware of its materiality. The manner in which the book is constructed, the way the sheets come together, the sequence of the pages, the existence of numbering, how sewn bound books are organized or how the sheets are attached to the spine, rarely attract the attention of the average reader. In the past, what we would now call a book had quite different characteristics.
