George Grayson's book is a full analysis of the oil sector in Mexican domestic and foreign affairs, covering PEMEX, labor aspects, the OPEC relationship, the Ixtoc blowout and more. The author remarks that there has been a remarkable and largely ignored record of cooperation in energy matters between Mexico and public and private groups in the United States. In the second book, these papers presented at a 1979 conference at Arizona State University are more diversified and representative than usual. The sections on Mexican and U.S. perspectives and changes in Mexico's external relations consist of basic papers, comments thereon and summaries of discussions.
