 Oxford University Press is in the process of producing a new edition of all of Locke’s works. This will supersede The Works of John Locke of which the 1823 edition is probably the most standard. The new Clarendon editions began with Peter Nidditch’s edition of An Essay Concerning Human Understanding in 1975. The Oxford Clarendon editions contain much of the material of the Lovelace collection, purchased and donated to Oxford by Paul Mellon. This treasure trove of Locke’s works and letters, which includes early drafts of the Essay and much other material, comes down from Peter King, Locke’s nephew, who inherited Locke’s papers. Access to these papers has given scholars in the twentieth century a much better view of Locke’s philosophical development and provided a window into the details of his activities which is truly remarkable. Hence the new edition of Locke’s works will very likely be definitive.
