In 1985, the first compact disc (CD) issue of the film score was made by the company Polydor Records, which had absorbed both RSO Records and its music catalog. Polydor Records used a shorter, one compact-disc edition of the music as their master. In 1993, 20th Century Fox Film Scores released a special boxed set of four compact discs: the "Star Wars Trilogy: The Original Soundtrack Anthology". This anthology included the film scores of all three members of the original "Star Wars Trilogy" in separate CDs, even though there was significant overlap between the three (such as the "Star Wars" theme music).
