In 1983, when he was 80 years old, Leo Gross compiled 45 of his essays which had been published in scholarly journals and other collections from 1945 to 1984. The collection was published in two volumes by Martinus Nijhoff Publishers and Transnational Publishers in 1984, with a Preface by Judge Stephen M. Schwebel of the International Court of Justice. The collection has been out of print for some time.;In response to many requests, the Publishers have now decided to issue a shorter, one-volume collection, the selection from the 1984 books having been carried out by Professor Alfred P. Rubin, who occupied the office adjoining that of Leo Gross in the Fletcher School for 17 years.;In his introduction to this one-volume collection, Alfred Rubin pays tribute to his former colleague and points to a number of the most impressive features of the Gross essays.
