Historians of miniature books keep on remembering previous forms of its existence – small clay planches made in Babylon more than 4000 years ago. So what is miniature book like? There’s no single definition. In USSR and now in Russia miniature book is an edition (in cover or in bookbinding), with maximum book face not more than 100 mm. The format of a book is pointed in mm, first number means breadth, second – height of edition. In other countries (USA, Great Britain, Germany, Hungary) these standards can’t surpass 3 inches, e.g. 76 mm. However among miniature books can be noticed micro-books which are even smaller 76. Notorious peculiarity of micro-book is no doubt, it’s size (not more than 10х10 mm), inability to read it with unarmed eye could be also pointed out, but everybody has different eye-vision! Invented in second half of XIX century photomechanical reproduction has made the opportunity to degrade text almost limitless.
