History: Early Years Of The Beatles

- 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).
- 2000s
The US album configurations from 1964–1965 were released as box sets in 2004 and 2006 (The Capitol Albums Volume 1 and Volume 2 respectively); these included both stereo and mono versions based on the mixes that were prepared for vinyl at the time of the music's original American release.
