The full work of The Early Asimov was published in English as a 3 volume set (Volume 1, 2, 3 [Panther, Doubleday, Granada]) and a two book set (Book One, Book Two [Fawcett/Crest, Del Rey]). The Dutch version was a three volume set broken down by years. The French and Italian versions were broken into 4 volumes, but it is unclear whether these versions contain the same stories per volume. As such, none of these should be mixed with each other nor should they be combined with the greater whole work. See http://www.isfdb.org/cgi-bin/title.cg...
