What is the world's smallest book?


Last week Toppan Printing Co. of Japan announced its creation of the world's tiniest book, measuring 0.75 by 0.75 mm. The images and lettering in this 22-page book on flowers are nearly microscopic, which is why a magnifying glass comes with the book for the purchase price of ¥29,400 ($308).

Toppan has been making miniature books since 1964, but this lilliputian book was made using high-tech currency printing techniques. It is currently on display at the Toppan Printing Museum in Tokyo. 

The company plans to apply to Guinness World Records for official recognition. The current record is held by a Russian book that measures 0.9 by 0.9 mm.
