Created around 1660, the Klencke Atlas is named by Guinness World Records as the largest engraved atlas. Guinness gives its closed dimensions as 178 cm high, 105 cm wide and 11 cm thick; open, it is 231 cm wide. The British Library gives the open atlas dimensions as 176 × 231 cm. It is more accurate to describe it as a record-setting atlas than as the largest book in general. [1, 2]
