Although Palm devices are not listed on the OCLC Supported Devices page,  I have been able to verify that you can listen to NetLibrary e-audiobooks on a Palm device using the PocketTunes application. There may be other applications that can play NetLibrary files, as well. PocketTunes will run on most Palm devices, including smartphones like the Treo.

Note that PocketTunes is not a free program, although, like most Palm applications, it is relatively inexpensive. The latest version (4.0) of PocketTunes Deluxe costs only $37.95, and the company is very good about giving users access to upgrades. PocketTunes Deluxe is the only version of PocketTunes that supports the WMA format used in NetLibrary e-audiobooks.

PocketTunes has a set of instructions for listening to NetLibrary e-audiobooks in their KnowledgeBase (they also have instructions for OverDrive), but as with many software applications, it may or may not work as described depending on the hardware and software environment. I have a Palm TX, and I upgraded my PocketTunes at the beginning of this process. I have Windows Media Player 11 installed on my computer. I encountered several errors, probably due to the PocketTunes upgrade. One remedy will be discussed at the end of these instructions.

1. The first step is to purchase and install PocketTunes on the Palm device. Note that although PocketTunes allows users to download a demo version, the demo version will not allow users to download and listen to e-audiobooks with DRM.
2. Connect to Windows Media Player. You need to make sure that this step works as you won't be able to proceed if it doesn't.
   1. Connect your Palm device to your computer, preferably using a direct connection to one of the computer's USB ports, rather than going through a hub, as this may cause errors later on.
   2. Open Windows Media Player.
   3. Turn on the Palm device and open PocketTunes while still connected to the computer.
   4. Windows Media Player should display the Palm device in the "Sync" area. You may see it in the drop-down box under the Sync button in WMP 11 or in the left-hand navigation in the main part of the screen.
3. Find and download a book from NetLibrary.
   1. Log in to NetLibrary, creating an account if necessary. You may need to log in through your public library's databases page or using a username/password combination that your library has given you.
   2. Find an e-audiobook that interests you.
   3. Select "download." If all goes well, the e-audiobook will begin downloading to your computer. These are very large files, so it make take some time. Remember the location that the book is downloaded to on your computer so that you can find it again.
4. Open the e-audiobook in Windows Media Player.
   1. First, verify that you still have an open session with NetLibrary (the login will time out in the time it takes to download a book). If you do not, log yourself back in.
   2. Open the e-audiobook in Windows Media Player. You may double-click the file or right-click and select "Open with Windows Media Player."
   3. When the e-audiobook is first opened, Windows Media Player will check to confirm that the license is valid. It took me several tries to get through this step, as I had to log in through my library, then log into my account.
5. Transfer the e-audiobook to the Palm device.
   1. Make sure that you have enough storage on your device for the e-audiobook. It will be the same size on the Palm as on the main computer, so it may need a substantial amount of space on a memory card.
   2. With Windows Media Player open, connect the Palm device, open Pocket Tunes and make sure that the device is recognized.
   3. Play the e-audiobook or see that it shows in the "Now Playing" screen of Windows Media Player (you can pause or stop the e-audiobook as long as it is listed in Now Playing.).
   4. Click the sync tab and select "Sync now playing to Palm device: DeviceName."
   5. Sit back and wait. The transfer should start immediately, but it will take a while.
6. Verify that the e-audiobook will play.
   1. Open PocketTunes.
   2. Select the e-audiobook and click "play."

Possible problems.

• By far the most common possible problem is that Windows Media Player refuses to see PocketTunes as a valid player. PocketTunes has several pages of things that may cause problems, ranging from hardware to software issues.
• Check the error code. I received the error message "Unknown MTP Error (0x8004C03E)" when I tried to transfer the file. This is a device mis-match code -- basically, Windows Media Player thought that the device wasn't really what it claimed to be, possibly because I had upgraded PocketTunes. The instructions at PocketTunes for this specific error message fixed the problem. If you get an error code, try searching the PocketTunes KnowledgeBase, and possibly the Web, for that specific code.
