History: Early Years Of The Beatles

• CD releases
- 1980s
The Beatles' studio albums were released on CD by EMI and Apple Corps in 1987. With their release, the band's catalogue was standardized throughout the world, establishing a canon composed of the twelve original studio albums as issued in the United Kingdom (listed above), as well as the US album version of Magical Mystery Tour (1967), which had been released as a shorter double EP in the UK. All the remaining material from the singles and EPs which had not been issued on the original studio albums was gathered on the two-volume compilation Past Masters (1988).
