King County Library System - eCollection - Home. How amazingly cool. King County now has a deal where you can download IMAX and other films onto your PC. Check them out and watch them. They also do classical music and books-on-tape as well.
These do use Windows encryption so they won't work on your iPod 🙁 but will work on your PC or if you really need to you can buy a Creative M:Vision or other iPod clone that uses Windows Media formats.
