Physical Studies of Minor PlanetsScientific and Technical Information Office, National Aeronautics and Space Administration, 1972 - 687 Seiten " ... Some papers and discussions included in this book even though they were not presented at the meeting. In some respects, therefore, the book is independent of the colloquium. Several papers had been invited long beforehand with the request to publish them as review papers. The lack of a modern textbook on minor planets is keenly felt, and the proceedings of this meeting, with these additions, should provide a good reference book."--Page viii. |
