This list was first published in the second edition of the Antarctic Pilot (London, Hydrographie Department, 1948, p. 6–25). Since that time it has been possible to make a large number of important corrections and additions. A check-list of this kind has been found necessary for classifying original log books, published narratives and other documents connected with the expeditions. It is hoped that it will also prove of value to those engaged in Antarctic research who may wish to check which expeditions have visited any particular area.
