This is the 'grandparent' of reference books in the field of international security. For nearly 40 years, the SIPRI Yearbook has consistently provided researchers and laypeople alike with clear, concise, and unbiased information on the arms trade, military assistance programs, armed conflict, and so much more. This year's volume is organized into three broad areas: 'Security and Conflicts,' 'Military Spending and Armaments,' and 'Non-proliferation, Arms Control and Disarmament'...An excellent glossary in the beginning introduces common abbreviations and international organizations (giving Web addresses). A well-done index concludes the volume...Highly recommended.
