(CNN) - As he campaigned for the White House in 2008, President Obama raked in millions of dollars in book royalties, according to recently filed Senate disclosure forms.
The president earned close to $2.5 million last year from royalties from 2006's The Audacity of Hope and 1995's Dreams from My Father, according to his Senate disclosure forms, filed with the Secretary of Senate's office earlier this week.
The Audacity of Hope - first published in paperback last summer - earned him $1,512,933, while Dreams of My Father earned $950,000.
An attachment to the disclosure form also reveals Obama agreed to a $500,000 advance days before his inauguration for an abridged version of Dreams from My Father "suitable for middle grade or young adult readers."
The president has also agreed to pen a non-fiction book for the Crown Publishing Group after he leaves office. A dollar figure on that advance has not been worked out.
