The list of the top fifty best-selling albums of 1975 was published in Music Week in the issue dated 27 December 1975 and in Record Mirror & Disc magazine in the issue dated 10 January 1976, and reproduced in the first edition of the BPI Year Book in 1976. However, in 2007 the Official Charts Company published album chart histories for each year from 1956 to 1977, researched by historian Sharon Mawer, and included an updated list of the top ten best-selling albums for each year based on the new research. The updated top ten for 1975 is shown below.[5]
^Greatest Hits was not eligible for the album chart until July 1975, as television-advertised compilations were excluded from the chart until this date. Most of the album's sales were during late 1974 and early 1975, and by the time it was readmitted to the album chart its sales had tailed off. The album did not officially reach number one until September 1977, following Presley's death.
