'Surprisingly revealing' The Sunday Times

We see notebooks everywhere we go. But where did this simple invention come from? How did they revolutionise our lives, and why are they such powerful tools for creativity? And how can using a notebook help you change the way you think?

In this wide-ranging story, Roland Allen reveals all the answers. Ranging from the bustling markets of medieval Florence to the quiet studies of our greatest thinkers, he follows a trail of dazzling ideas, revealing how the notebook became our most dependable and versatile tool for creative thinking. He tells the notebook stories of artists like Leonardo and Frida Kahlo, scientists from Isaac Newton to Marie Curie, and writers from Chaucer to Henry James. We watch Darwin developing his theory of evolution in tiny pocketbooks, see Agatha Christie plotting a hundred murders in scrappy exercise books, and learn how Bruce Chatwin unwittingly inspired the creation of the Moleskine.

On the way we meet a host of cooks, kings, sailors, fishermen, musicians, engineers, politicians, adventurers and mathematicians, who all used their notebooks as a space for thinking and to shape the modern world.
