Yeah, but books have no air.

Things with air in them weigh a lot less. Those books probably weighed more
than you think. Infact, by the cubic foot, paper weighs more than wood
(because wood has more air and than paper fiber). For the cubic space
occupied by those books you probably could have hauled 2 or 3 times as much
wood (thus filling your minivan completely with wood?).
