Sotomayor reported the payment for the as-yet untitled book from Knopf Doubleday Publishing Group in her annual report of personal finances, released Friday for the justice and her eight colleagues. Knopf revealed last July that Sotomayor had agreed to write the memoir, but the size of the advance had not been known.
Justice Clarence Thomas also received more than $1 million in advance of the publication of his book, "My Grandfather's Son" in 2007.
Thomas reported that his wife, Virginia, received salary and benefits from two conservative advocacy groups she created, Liberty Central and Liberty Consulting. The amounts were not disclosed.
