Thanks, amylou. We have tried the public library downloads. Some problems with this included really long wait times, we can only check out a few things at a time, there's a rotten interface (truly confusing and lots of errors), and, as you said, we are limited to the ones in mp3 format since we use a Mac with OSX. So the audio downloads from the library are, right now, not a great solution.
I think this will significantly improve in upcoming years, but am looking for a good solution in the meantime:)
