Grammy Award for Album of the Year

The Grammy Award for Album of the Year is an award category at the Grammys. 
History.
It has been awarded since 1959, and while originally awarded only to the artist, the award is now given to the artist, the producer, the engineer and/or mixer and mastering engineer. In 1962, the name of the award was expanded to Album of the Year (other than classical) but it returned to the shorter name in 1965. It was not until until 1968, 1999, and 2002 that the award was won by a rock album, a hip hop album, or a country album, respectively.
Winners.
Frank Sinatra, Stevie Wonder, and Paul Simon are the biggest winners in this category with 3 wins each. Paul McCartney leads all artists with 9 nominations: 5 as a member of The Beatles, 3 for solo albums, and 1 as a member of Wings. Frank Sinatra leads solo artists with 8 nominations, 7 for solo albums and 1 for a duet album. Paul McCartney and Paul Simon are the artists with the most nominations in most decades, 5 - the 1960s, the 1970s, the 1980s, the 1990s and the 2000s, if counting 1960s nominations as part of their respective groups, The Beatles, and Simon &amp; Garfunkel.

Differences.
Many wonder what the difference is between Record of the Year and Album of the Year. Record of the Year is awarded for either a single or an album track. This award goes to the performer, producer, recording engineer, and/or mixer for that song. Album of the Year is awarded for an entire album, with the award being given to the artist, producer, recording engineer, and mastering engineer for that album. So, in this context, "record" means one song and "album" means the entire collection of songs on a CD or LP.
Unlike Record of the Year, which goes to the artist and production team of a single song, Song of the Year goes to the songwriter(s) of the song. Therefore, Record of the Year is awarded to the best "recording".
