'There are some books that experienced IHL scholars and practitioners keep within arm's reach - International Humanitarian Law by Nicholas Tsagourias and Alasdair Morrison sits at the top of that list. Its comprehensive, up-to-date collection of IHL-related material, with commentary, is an indispensable resource for anyone doing IHL research, from students and faculty to government andnon‑governmental legal advisers.' Michael Schmitt, G. Norman Lieber Distinguished Scholar, West Point
