Yemen and the Gulf States: The Making of a Crisis, an edited volume by Helen Lackner and Daniel Martin Varisco, provides six chapters presented in a workshop on Yemeni issues at the Gulf Research Meeting 2016 held in Cambridge, UK. The chapters address both domestic and international aspects of the ongoing conflict, namely the Iranian, Omani, Saudi, and Gulf Cooperation Council (GCC) dimensions of the crisis. The six chapters are selected out of thirteen papers presented in the workshop. However, Lackner keeps his readers in the dark regarding the basis on which the chapters were selected, despite providing synopses of the content of the papers. Although the exclusion of the remaining papers is within the discretion of the editors or publishers, transparency about the selection process would have served to clarify why the book is structured as it is.
