The Beatles Box Set is the first complete set of original Beatles material released by EMI and Capitol (catalogue number BBX2-91302) in compact disc format. Issued in 1988, the entire digitally formatted Beatles catalogue could be purchased in a single set for the first time. The boxed set, available on CD, vinyl LP or cassette, included all of the original UK Beatles releases. It included the album version of Magical Mystery Tour, which had been issued in the United States in 1967 as an LP but never released in the UK in this format until 1976, when the US LP version superseded the original British EP. The box also contained the new 1988 compilations Past Masters: Volume One and Past Masters: Volume Two, which featured singles, B-sides, EP tracks, and foreign releases not found on the original albums. Although all the original UK albums had been previously available in stereo on both LP and cassette, the versions of the first four albums included in The Beatles Box Set were the digitally remastered mono mixes issued on CD in 1987.
The collection was encased in a black oak roll top box and included a soft-cover book with commentary on the songs by Mark Lewisohn. The set was also issued in a black vinyl covered cardboard box in Japan.
A new Stereo Box, containing remastered versions of the Beatles' core albums and Past Masters, was released on 9 September 2009 along with The Beatles in Mono and new stereo reissues of the individual albums, including the first four albums given their stereo debuts on CD.
