Book excerpt: What do you use every day that is small and large, worthless and beyond price? It's easily found in the gutter, yet you may never be able to replace it. You are always losing it but it faithfully protects you; sexy and uptight, it is knitted in to your affections or it may give you nightmares. It has led to conflict, fostered and repressed political and religious change and epitomizes the great aesthetic movements. It's Eurocentric, and is found all over the world. On the Button is an inventive and unusual exploration of the cultural history of the button, illustrated with a multiplicity of buttons in black and white and colour. It tells tales of a huge variety of the button's forms and functions, its sometimes uncompromising glamour, its stronghold in fashion and literature, its place in the visual arts, its association with crime and death, its tender call to nostalgia and the sentimental. There have been works addressed to the button collector and general cultural histories. On the Button links the two, revealing why we are so attracted to buttons, and how they punch way above their weight.
