Most of the search directories no longer worked for me. I finally lucked out with the Education Podcast Nework. I found a podcast by David Warlick, whom I had heard about. He interviewed a Bombay school librarian, Ann Krembs, about creating a
virtual library.
It looks much like Joyce Valenza's but with a few twists.
I then went to my google reader and located David Warlick's podcast feed and added it to my other feeds so that I can automatically see what he does next.
