Edited by Peter Davison. Consists of 20 volumes in total. The first 9 being Orwell's standard published works and the final 11 a compilation of the rest of Orwell's entire literary output.

These are usually referred to in Roman numerals eg. 'CW XIV', and so on. The CW was originally only available as a prohibitively expensive hardback set, but Secker and Warburg have begun publishing the final 11 volumes as individual paperbacks (this reprint also corrects some typographical errors in the original and adds a few minor items). At the time of writing, only published in the UK (though available elsewhere through online distributors). Has supplanted the CEJL as the most authoritative edition of Orwell's work.
