Exploring Creation with Biology - Audio Book MP3-CD

The CD will work in a computer or a MP3 compatible CD player. It will not run in a CD player that is not MP3 compatible. If your CD player is MP3 compatible, it will say so right on the CD player. The MP3 compression allows the entire book to fit on one CD. Without MP3 compression, it would take approximately 16 CDs to hold audio of the entire student text!
