In 2008 Rzeszów University published a jubilee book inscribed to Prof. Kazimierz Obodyński. In order to make this book both exceptional and educational as well as to pay respect, a lot of effort was put into publishing it. Its creators included Prof. W.J. Cynarski, Prof. A. Nowakowski and Prof. S. Zaborniak. They have given the book a clear structure and a good order of materials. The jubilee book is a sign of great scientific friendship and respect of colleagues and students towards Prof. Obodyński.
