The podcast I am including is entitled "A Natural History of Chicano Literature: a Performance Lecture by Juan Felipe Herrera." This podcast is part of the University of California Television's site (http://www.uctv.tv/), which highlights podcasts such as documentaries, lectures, and other performances. A listing of other related podcasts available for download can be found at http://www.podcastblaster.com/directory/podcast-1175.html.
I found this podcast using the Yahoo! Podcast search engine at http://podcasts.yahoo.com/.
I selected this particular podcast because it highlights an author who has had much success writing for children and young adults. Specifically, Juan Felipe Herrera and his work have been recipients of the Ezra Jack Keats Award, the Americas Award, and the Pura Belpré honor award. As this podcast relates to children's and young adult literature from the perspective of an author with whom school librarians should be familiar, I felt it was an appropriate example of how podcasts can help present information on a variety of topics and from a variety of perspectives.
