Michael Wood, Intern October 2006 [review of the second edition] 55, Part4,
The arrival of a second edition of James Crawford's seminal monograph is a welcome event...the second edition is more comprehensive and has a greater depth than its predecessor. Finally, although the first edition was very well received, in the intervening period Crawford has become a leading figure in international law...Crawford provides a meticulous, almost encyclopedic, account of a wide range of issues which inform the legal concept of statehood in modern international law.
