The release of the book, Birgiman Hankaka 1, by Adamu Aliyu Kiyawa, an educationist and veteran radio broadcaster/journalist in Kano recently has provided Hausa readers across the country an opportunity to benefit from the enormous information and knowledge that had hitherto been the exclusive of radio listeners in Kano. The 105-page publication is a reproduction of his popular weekly radio talk show, "Birgiman Hankaka", aired on Freedom Radio Kano, and anchored by the veteran broadcaster in Kano state.
