      I edit five dictionaries published by Oxford University Press. Oxford Dictionary of Plant Sciences and Earth Sciences (now retitled Geology and Earth Sciences) are in their fourth editions, and Ecology and Zoology are in their fifth editions (Ecology is online only) The newest dictionary is Environment & Conservation, which I have inherited from Chris Park, who prepared the first edition; the second edition appeared in 2013 and the third edition (online only) in 2017.
