In 1997, the record company RCA Victor released a definitive two-CD set to accompany the publications of all three of the Special Editions of the films of the "Star Wars Trilogy". This original limited-edition set of CDs featured a 32-page black booklet that was enclosed within a protective outer slip-case. The covers of the booklet and of the slip-case have selections from the poster art of the "Star Wars Trilogy: Special Edition". All of the tracks have been digitally re-mastered supposedly for superior clarity of sound.
