They include a handwritten list of songs and speeches planned for the funeral as prepared by gospel singer JD Sumner, whom Elvis' father personally asked to organise the ceremony, attended by James Brown, Ann-Margret and George Hamilton, reported New York Post.
A day before the funeral, 30,000 fans attended a public viewing at Graceland.
The White House had to send in 300 National Guard troops to maintain order.
Sumner's notes come with a personalised Bible given to him by TV evangelist Reverend Rex Humbard, who officiated at the rite.
