Colloquium No. 72 of the International Astronomical Union covered many observations and theoretical developments in the field of cataclysmic variables and related objects. Much time was devoted to discussions and we made an effort to include as much of the discussions material as possible in the proceedings. The Local Organizing Committee would like to thank; The International Astronomical Union for travel grants The Israel Academy of Sciences for financial support The Technion-Israel Institute of Technology for financial support and assistance Bank Leumi Le-Israel for a generous support We also thank the Dean of the Faculty of Physics, our colleagues and students for their assistance.
