In their native United Kingdom during 1962–1970, The Beatles released 12 studio albums, 13 EPs, and 22 singles. However, the band's international discography is complicated, due to different versions of their albums sometimes being released in other countries, particularly during their early years on Capitol Records in the United States.

Although their output has come to include vault items and remixed mash-ups, the core Beatles discography recorded during the 1960s is 217 tracks and approximately ten hours of music. Most of The Beatles' albums were released in both mono and stereo. Since mono record players were the most common at the time, The Beatles and their regular producer George Martin gave more time and attention to preparing mono mixes of their recordings. The Beatles had only involved themselves in creating the mono mixes for the first four albums; the stereo mixes were prepared without their supervision. However, because by the late '60s stereo record players became more common, their final two albums—Abbey Road and Let It Be—were mixed and released in stereo only (source: wikipedia.org)
