I use the CNIB's digital library which has a link to Netlibrary. Will I be able to listen to Netlibrary's audio books on the BookPort? From Netlibrary Help: "NetLibrary's eAudiobooks can be listened to on a wide range of portable devices, including portable music players, portable media centers, Pocket PCs, and even select smartphone devices. In order to be considered a device that works with NetLibrary eAudiobooks, the only requirement is that the device must be able to support playback of secure or protected wma files. NetLibrary eAudiobooks are provided in two sound qualities, CD (34 kbps) and Radio (4 kbps) quality. Most devices do not support the playback of files lower than 32 kbps. When selecting a device you should make certain the device supports playback of at least 32 kbps files. If you are going to transfer and listen to an eAudiobook on a device you should download the CD quality file. To have an optimal experience when listening to a NetLibrary eAudiobook, it is recommended that you select devices that support features such as bookmarking and full time stamping. Also, devices that have a storage capacity of 256 MB at a minimum are recommended since the average CD quality eAudiobook file size is 140 MB. Devices that support bookmarking allow you to designate a place within a file and return to that place. Some devices limit time tracking to a pre-defined period of time and often eAudiobooks files may be longer than the pre-defined period in the device. In this case, the complete length of the file will not be shown in the device. Devices that support full time stamping do not limit the time tracking of a file in any way and will allow the full length of an eAudiobook file to display.". Reed
