My overworked iPod Shuffle

I made a quick visit to the Moorer Branch of the Mobile Public Library today and picked up 4 audiobooks to add to my collection that is growing in my iTunes library.

Founding Mothers by Cokie Roberts
The Beatles: The Biography by Bob Spitz
Ulysses S. Grant by Josiah Bunting III
Plan of Attack by Bob Woodward

They join the books I have already on there....

1776 by David McCullough
The Broker by John Grisham
The Secret Man by Bob Woodward
The DaVinci Code by Dan Brown

I love historical, biographical and current affairs CD audiobooks.....

Any recommendations??
