Montenegro, Spain, Switzerland and Tunis. Great Britain ratified only the additional act and not the interpretative declaration, while Norway, which had become a unionist country April 13, 1896, ratified only the interpretative declaration and not the additional act. Thus from December 9, 1897, the Berne convention and the Paris acts together constituted, with the exceptions noted, the fundamental law of the International Copyright Union.
Berlin con-
ference,
1908
A second conference for revision was called in 1908 by the German government, and met at Berlin October 14 to November 14, resulting in the signature on November 13, 1908, of a revised convention continuing or reconstituting the International Copyright Union and replacing by substitution the Berne convention and Paris acts in those states accepting it by ratification. To this conference the German government invited not only the signatory powers of the Union, then fifteen, —Belgium, Denmark (which had acceded to the Union in 1903), France, Germany, Great Britain, Haiti, Italy, Japan (1899), Luxemburg, Monaco, Norway, Spain, Sweden (1904), Switzerland, and Tunis; but also non-unionist countries, of which representatives were sent from twenty countries, —Greece, Holland, Portugal, Roumania and Russia, China, Persia and Siam, Liberia, the United States of America, Mexico, Guatemala and Nicaragua, Argentina, Chile, Colombia, Ecuador, Peru, Uruguay and Venezuela. The working committees were made up exclusively from representatives of the signatory powers, only these countries
participating in the votes; active participation otherwise was confined to representatives of countries expecting to become signatory powers, Holland and
Russia, while the other participants acted as observing representatives or supplied information on request.
