Since its first edition, there have been many significant changes to this work, including a new author and complete overhaul of the entries, and even a new publisher. Notably, the 300-plus topics covered are now focused almost exclusively on the organizations themselves with limited profiles of people, while the previous edition highlighted many more individuals. Furthermore, the organizations included in the new edition are more varied than in the earlier publication. This is probably due to the major geopolitical events of the past two decades, such as the 9/11 attacks, the Arab Spring, and the various wars and civil wars that have afflicted the Middle East, as well as the proliferation of new organizations responding to the changing conditions. As well, many organizations covered in 2001 are not retained here, some presumably having lost significance in the interim. The work under review primarily focuses on countries of the Middle East and North Africa (MENA); a few exceptions are also included, such as Afghanistan. The dictionary covers a selection of both major and minor intergovernmental organizations and NGOs working in the region. In view of the many new organizations covered in this book and the exclusion of many from the first edition, libraries should retain both editions. Recommended.
