Along with the individual interview podcasts available at http://www.aasv.org/members/only/pod/, AASV members may now download a "disk image" containing all thirty speaker interviews from the 2009 Annual Meeting plus the audio from three keynote lectures and the four "Learning from the Best" speakers in the general sessions — over 12 hours on one CD.
Most recent recent car/truck stereos include the ability to play back MP3 files from CD-R discs you record on your computer — look for a "mp3" logo on the unit or mention of mp3s or ISO-9660 format in the manual. Additional instructions are online.
(I have been unable to find a method of putting files for traditional audio CDs on the web site. I’m guessing you wouldn’t really want to lug around a stack of ten of them anyway.)
