Slowest selling book
David Wilkins translation of New Testament
UK (Oxford University Press)
The accolade for the world's slowest-selling book (known in US publishing as slooow sellers) probably belongs to David Wilkins' translation of the New Testament from Coptic into Latin, published by Oxford University Press (OUP) in 1716 in 500 copies. Selling an average of one each 20 weeks, it remained in print for 191 years.
