Linda Fox, who attended my CDLC presentation on Monday, suggested two great podcast diectories.
The Education Podcasting Network links to podcasts created by various educational institutions, including elementary schools, middle schools, high schools, & higher ed. They also group them by subject, including health, English, second languages, and social studies. Worth checking out if you want to see how to use podcasts in your school!
The Podcast Network publishes its own podcast content -- similar to a radio or television network, but for podcasts. You can get some of them in iTunes, but this web site shows all of them and lets you subscribe to their content. Very independent.
