I am guessing, but Shlomo Ketko was my supervisor when I spent a year at Hebrew University for a ''One Year Israel Training Course... etc.'' in 1976, and the author was thorough, very knowledable, communicative, in short, had all those qualities needed to convey a message to a wide audience. Since the title of his work corresponds with my experience I can only guess that it is highly readable, I know for sure it is based on a long and deep understanding and love for his topic!
