The Oxford International Encyclopedia of Peace, edited by Colgate Professor Nigel Young is simply excellent. Its over 900 entries cover about anything you can think of when it comes to research on peace, conflict, war, violence and all what has to do with it. From Gandhi’s influence on the peace movement, to short biographies of key figures of war and peace to various subquestions of social science research on peace and war (such as democracy and war or aid and peace), it contains all in short, well written and yet well balanced articles with a select and sufficient number of further recommended readings and cross-references. It’s a wonderful tool for teaching but also as quick reference for research if some detailed information is needed on a concept, event, person, institution or direction of former reseach. Highly recommendable!
