Together with an 18th-century directory of sex workers in the Covent Garden area of London, and the violent erotic works of the Marquis de Sade, the Merryland books are among the 2,500 volumes in the British Library’s Private Case collection. The volumes have now been digitised, and are being made available online by the publisher Gale as part of its Archives of Sexuality and Gender academic research resource. – The Guardian
