Clarendon press is a book publisher based in Oxford, England. The Oxford University Press came to be known as "(The) Clarendon Press" when printing moved from the Sheldonian Theatre to the Clarendon Building in Broad Street, Oxford, in 1713. The name continued to be used when The Oxford University Press moved to its present site in Oxford in 1830. The label "Clarendon Press" took on a new meaning when The Oxford University Press began publishing books through its London office in the early 20th century. To distinguish the two offices, London books were labelled "Oxford University Press" publications, while those from Oxford were labelled "Clarendon Press" books. This labelling ceased in the 1970s when the London office of The Oxford University Press closed. Today, The Oxford University Press reserves "Clarendon Press" as an imprint for Oxford publications of particular academic importance.
