The Berlin convention included thirty articles, covering the same ground as those of the Berne convention and the Paris acts, but somewhat differently arranged, so that comparison is not quite direct. Article 1 reconstitutes the International Copyright Union. The expression "literary and artistic works" is defined (arts. 2 and 3, covering previous arts. IV-VI) as including "all productions in the literary, scientific or artistic domain, whatever the mode or form of reproduction, such as: books, pamphlets and other writings; dramatic or dramatico-musical works; choregraphic works and pantomimes, the stage directions ('_mise en scene_') of which are fixed in writing or otherwise; musical compositions with or without words; drawings, paintings; works of architecture and sculpture; engravings and lithographs; illustrations; geographical charts; plans, sketches and plastic works relating to geography, topography, architecture, or the sciences. Translations, adaptations, arrangements of music and other reproductions transformed from a literary or artistic work, as well as compilations from different works, are protected as original works without prejudice to the rights of the author of the original work." The contracting countries are pledged to secure protection fully for these categories and for photographic works and "works obtained by any process analogous to photography" and to protect "works of art applied to industry" so far as domestic legislation allows. {Sidenote: Authors' rights} {Sidenote: "Country of origin"} The convention assures (art. 4, broadening art. II) to authors within the jurisdiction of a unionist country for their works, whether unpublished or published for the first time in one of the countries of the Union, such rights in each other unionist country as domestic laws accord to natives, as well as the rights accorded by the convention, "not subject to any formality" and "independent of the existence of protection in the country of origin," and regulated exclusively according to the legislation of the country where the protection is claimed. The "country of origin" is defined as "for unpublished works, the country to which the author belongs; for published works, the country of first publication" and for works published simultaneously in several countries within the Union (as also in countries without the Union), the unionist country granting the shortest term of protection. Published works (_oeuvres publiees_) are again defined as works that have been issued (_oeuvres editees_). "The representation of a dramatic or dramatico-musical work, the performance of a musical work, the exhibition of a work of art and the construction of a work of architecture do not constitute publication." {Sidenote: Broadened international protection}
