The Beatles Collection is a box set of the Beatles' vinyl albums released in the United States in November 1978 and the following month in the United Kingdom.
It included only those albums which were then official canon, hence did not include Magical Mystery Tour (the only canon version at the time was the double EP), nor any of the compliation albums. It did, however, contain an additional album called Rarities.
The American release was a limited edition of only 3,000 copies, and included a different Rarities album. For the former reason, many US fans imported the British version instead.
