The laborious bulk translation was taken care of by the students Janne Tamminen (TUT) and Kung-Chung Lee (visiting from the University of British Columbia). Most of the material was then checked by professor Robert Piché. I want to thank the translation team for their effort. 

The notes form the base text for the course "MAT-62756 Graph Theory". They contain an introduction to basic concepts and results in graph theory, with a special emphasis put on the network-theoretic circuit-cut dualism. In many ways a model was the elegant and careful presentation of SWAMY & THULASIRAMAN, especially the older (and better) edition. There are of course many modern text-books with similar contents, e.g. the popular GROSS & YELLEN.
