For $20,000 US you can lay claim to a limited edition of the World’s Smallest Book. It measures less than 0.1 millimetres square! It was created with a laser beam etchings on a silicon crystal (nanotechnology). Incredible!
A gang of Canadian physicists have created some reading material that could give you serious eyestrain. The tiny book, less than 0.1mm square, was made by etching letters onto 30 slices of polished silicon crystal using a focused ion beam. The book even has its own ISBN, and you can buy a limited signed edition for around $US 20,000 - but don't forget to set some money aside for the electron microscope you'll need to read it with.
