"The material presented here originated in lectures given at summer schools in Les Houches and Edinburgh in 1960, but these notes represent an extensive revision of and addition to the contributions of my contribution to the published proceedings of the seminars. The most important additions center around the double spectral function, whose role in the S Matrix has been substantially clarified during the past year. This clarification has sharpened the distinction between elementary and composite particles, a distinction that is now becoming the central problem of strong-interaction physics."
