Before you make your decision, Obama's book is much shorter than the rest. No, not because he's only had two years in office as opposed to eight, but because it's a Children's book.
There's controversy over whether or not it's even appropriate for a president, in office, to even release a children's book - especially one about politics. Does that constitute political indoctrination? That's up for each individual parent to decide.
That being said "Of Thee I Sing" is a book that is written to Obama's young daughters. We haven't seen such young children in the White House since the Kennedys.
According to various reports, the President wrote the book between the time when he was campaigning for the presidency and when he took office - before he took control of the country.
Proceeds of the book will be donated to families of injured military personnel, and there's no plans for the President to do a book tour.
