    Dear Bill,
    Thank you very much for your response.
    I have, though, already seen this WEB site earlier and obtained a copy of the
    1929/30 publication in the New Zealand Journal of Science and Technology,
    which up to now has been one of my prime sources on the history of the IDL.
    I recently came across another useful source for the history of the IDL prior
    to 1900 in:
      H.M. Wallis & A.H. Robinson, Cartographic Innovations: An
      International Handbook of Mapping Terms to 1900 (Map Collector
      Publications, Londen, 1982), art. 'Date Line'.
