If you have an iPOD you can easily transfer your Audio Book to your iPOD via iTunes
When you insert a new disk into your disk drive (after you have iTunes running) you get this screen (we are importing Stephen Kings Dark Tower II Audio Book)
If you answer "yes" it will start importing the tracks - you get a progrss bar at the top while your Audio Book is being imported to iTUNES
This is the screen when completed (all the tracks on the left are marked green) - you can now transfer the tracks over to your iPOD
