3d ed., l6mo, 155 p.) is a brief compilation of and comment on these laws of 1901 and 1910. The most recent and authoritative general works are Prof. Josef Kohler's "Urheberrecht an Schriftwerken und Verlagsrecht" (Stuttgart, F. Enke, 1907, 527 p.), though some of his statements of theory have given rise to criticism and dispute, and his "Kunstwerkrecht" (Stuttgart, Enke, 1908, 191 p.), Daude's "Die Reichsgesetze über das Urheberrecht an Werken der Literatur und Tonkunst und das Verlagsrecht" (Berlin, Guttentag, 1910, 293 p.), and Dr. Albert Osterrieth's "Das Urheberrecht an Werken der bildenden Künste und der Photographic" (Berlin, Heymann, 1907, 312 p.).
