This volume is devoted to HERA physics (HERA is the electron-proton collider at DESY, Hamburg). The lectures cover the main areas of current research in the field of deep inelastic scattering at high energies, at both the theoretical and the experimental level. Particularly interesting are the presentations on data from both HERA experiments, namely H1 and ZEUS.

The Salamfest was held to honor Prof Abdus Salam whose scientific contribution to the development and dissemination of physics has deeply influenced the course of scientific advancement. Colleagues, collaborators and former students met together to celebrate his scientific achievements, and discuss the highlights of recent advances in experiment and phenomenology in particle and condensed matter physics.The Contributors are: A Ali, G Altarelli, L Alvarez-Gaumé, D Amati, J Bahcall, A Chamseddine, R Delbourgo, M Duff, J Ellis, J Feltesse, P Frampton, M Green, G 't Hooft, T Kibble, G Mack, Y Ne'eman, L O'Raifeartaigh, J Pati, R Peccei, S Randjbar-Daemi, Riazuddin & Fayyazuddin, D Schramm, H Schröder, D Sciama, E Sezgin, Q Shafi, C Vafa, S Weinberg, P West, B Winstein, E Witten, C N Yang, A Zichichi and B Zumino.

This volume reviews the recent progress of B physics, and discusses theoretical and experimental aspects of the physics which will be explored at the B factory. CP violation and new physics beyond the Standard Model are the main issues of the discussion.

Proceedings of a conference held in Ithaca, New York, in August 1993. Topics included status of rare kaon decay experiments, nucleon structure from fixed target experiments, measurement of the LPM effect, charm decay physics, recent bottom physics results from threshold machines, an overview of heav
