The December presentation for 50 Minutes-1 Book features CCM Librarian Mark Palkovic talking about the new “World’s Smallest Book!” It is a 22-page micro-book measuring just 0.75 millimeters (or for the metric-impaired, 0.03 inches). Entitled Shiki no Kusabana, this book of flowers was published by Toppan Printing in Japan. Toppan printed the volume using its ultrafine printing technology, the same method used to avoid forgery of paper currency.
