Work on the "Buildings of England" series began in 1945, and the first volume was published in 1951. Pevsner wrote 32 of the books himself and 10 with collaborators, with a further four of the original series written by others. Since his death, work has continued on the series, which has been extended to cover the rest of the United Kingdom, under the title Pevsner Architectural Guides (now published by Yale University Press). After updating and correcting "London 1: the Cities of London and Westminster" for its reissue in 1962, Pevsner delegated the revision and expansion of further volumes to others, beginning with Enid Radcliffe for "Essex" (1965). The gazetteer descriptions of revised volumes do not routinely distinguish between Pevsner's original text and any new writing, but more recent books sometimes supply his words in quotation when the revising author's judgement differs, where a building has since been altered, or where the old text is no longer topical.
