The Cracow School on Cosmology was held in Jodlowy Dwor and it was devoted to discussions of physical processes playing an important role in development and revealing the structure of universe. Methods used to study distribution of galaxies were also presented. I regret but I failed to persuaide Drs. M. Kalinkov and A. Kruszewski to write up their lectures.
The School was sponsored by Committee of Physics of the Polish Academy of Sciences, Jagiellonian University and Polish Astronomical Society. I would like to thank all those Institutions for their help.
I am deeply grateful to all lecturers and participants for creating a very good atmosphere and to Drs. P. Flin, Z. Klimeic and L.Sokolowski for organizing the School.
I would like to dedicate the Proceedings to the memory of Dr. Z. Klimeic who tragically died a few days before beginning of the School.
