Show Archives are missing a lot of episodes

Hello! I was looking for names and descriptions of some old episodes that I have saved in my podcast and noticed a whole bunch of episodes are missing from this page: http://www.cartalk.com/our-show/browse.

For example, I have the episode “Car Talk 0949 December 5, 2009” in my podcast stream but could not find the name and description in the 2009 list on the show archives. There are only two episodes listed for 2009 on that page. Anyone know why all the other 2009 episodes are not listed?

Can anyone please point me to the complete list of all episodes ever aired? (with name, date, and description)

Many thanks in advance!

I can only guess that they have been re-run more recently, and thus re-dated.
