<p style='text-align: justify;'>A combination Latin dictionary and encyclopedia completed in 1286, the Catholicon of Giovanni Balbi was the first non religious book of substantial size to be printed. The 1460 edition, the first of many 15th century editions, contains in its colophon the first detailed printed reference to the introduction of printing with moveable type. This is also the first instance in which a book named its place of printing. Although the name of the printer is not given, the particular nature of the working and other evidence have led people to believe that this edition must have been printed by Johann Gutenberg -- Library of Congress.</p>
