Why don't you have more MP3 titles?
The publishers’ control what titles are placed in our vendors catalog and in what format they are allowed to be purchased in.
Please be assured that HCPL purchases every eAudio title in the MP3 format first whenever possible. Most of the bigger audiobook publishers do not put their titles in the MP3 format through our vendor. Most choose to only add their titles in the WMA format.
The reasoning behind this, as far as I am aware, is that the MP3 titles do not have as many copyright protections embedded in them. The three largest audiobook publishers, Random House, Books on Tape, and Brilliance, only add their titles as WMA. Again, we will purchase the MP3 format over the WMA format whenever the option is available to us.
