As Eric said, Listen Up Vermont! is a great resource for audio books if your
town library has a membership. You have to install the OverDrive Player and
upgrade the security in order to download. http://www.listenupvermont.org/.
Many books can also be burned to a CD. You do not need to use iTunes,
although you can.
This is slightly off topic but is in line with assistive technology. It is a
tool for literacy support that I came across yesterday.... MyStudyBuddy. It
is essentially like the Read Write Gold toolbar. It has text to speech with
highlighting, word prediction, voice recognition (only on Windows 7), and
many more tools and features. It is totally free.
If you have already purchased extra voices, it can use those!
