I Dictionaries, histories and philosophies of geographyFuture writers on the history and philosophy of geography will find some of the most illuminating and invaluable records of the intellectual journeys taken by the discipline in the late twentieth century in the pages of The dictionary of human geography, now in its fourth edition (Johnston et al., 2000). This increasingly bulky book provides an essential atlas and gazetteer to the contemporary (and largely Anglo-American) geographical landscape. As such, it may be read in a range of directions and offers insights into key technical, methodological and philosophical terms, fostering new connections and creative cartographies of an ever-expanding intellectual universe. Given the scope and key reference status of the volume, as well as its direct role in shaping and reflecting the history and philosophy of geography, I would like to consider this new edition in greater detail than is usually the case for individual works in progress reports. I shall then go on to use this as a basis for considering, in more general terms, work in the history and philosophy of geography in 1999-2000.As the editors note in their preface, since the first edition (1981) The dictionary of human geography has acted as 'both mirror and goad . . . both reflecting and provoking work in our field' (Johnston et al., 2000: iv). This revised and expanded fourth edition is further proof of the diversity of contemporary human geography, with over 900 entries written by 57 contributors (compared to the first edition's 500-plus entries written by 18 contributors). With over 200 new entries and extensive revisions and updates, it seems that geography in the twenty-first century is characterized by ever greater vicissitude in philosophy and accelerated change in terminology. (The wordiness of human geography entries is made apparent by the fact that, though it has half the number of entries of its physical geography counterpart (Thomas and Goudie, 2000), The dictionary of human geography is an additional 350 pages in length.) Many geographical subdisciplines now generate their own specialized 'handbooks' (see, for example, Clark et al., 2000). Even updates of classic textbooks such as Arild Holt-Jensen's Geography -history
