MY personal collection of World Politics begins with the January 1957 issue: volume 9, number 2. It skips to October 1964 and is complete from then on. When I left Princeton to become Northwestern University's fifteenth president, I gave away most of my professional library, envisioning all too accurately the demands of a new life. I never considered parting with any copies of World Politics, however. Perhaps in part this sense of possession came from sentiment arising from my long and happy association with this journal. I think, however, that it stemmed mostly from a recognition that World Politics has been the leading journal of international affairs and comparative studies from its founding until now.
