Imported Audiobook

Hey, I had a quick question for anyone that knows... I imported an audiobook from a CD into iTunes, but cannot get iTunes to recognize it as an audio book, this would be better for my iPod etc. How does it tell downloaded audiobooks apart?<br><br>

Re-import the CD as one big AAC file using the "Join CD Tracks" option under the Advanced menu. Then use this script to make that AAC file a bookmarkable track, so iTunes and iPod can treat the file as an audiobook.<br><br>

Ya, It's already like that though, but as an mp3, can I convert it?<br><br><br>
