Dear Colleagues, Help! - can someone enlighten me and provide the full reference to "Lab. Geol. Nucl. Pisa" This abbreviation appears as the publisher in the Craig and Gordon 1965 paper on deuterium and oxygen-18 variations in the ocean and marine atmosphere. I need, if possible, to find the full version of this abbreviation and include the country (Italy?). I have tried Georef and some other bibliographic database searches with no success. Len
