I enjoyed this thing and learned quite a bit, too. I have used podcasts before and have subscribed to one or two, but podcasts are not among my more widely used online tools. Like most things it comes down to subject matter: find something you like and chances are, you'll stick with it, otherwise,you're gone!
Initially, I used the libsuccess.org site to select a podcast from the Denver Public Library. Randomly I selected the first item on the list: The Pig Who Went Home on Sunday :An Appalachian Folktale by Donald Davis. It was a reading of a children's book. The narrator did a good job, but sadly I can not tell you how the story ended. I can tell you that it was a take-off of the "Three Little Pigs" saga and that the sly fox had dinner with the first pig. Menu was pork. Oh well, kids will love it.
My second selection from the libsuccess.org list was a podcast from the Lincoln (Nebraska) City Library. Sound quality was excellent... for the introduction. The intro consisted of a lovely classical music piece followed by an announcer that came direct from WRR radio. His tone was deliberate and pretentious. His words were hushed; he quietly mouthed the announcement as though he were in a library, or perhaps at a golf tournament. With great expectations the program began. What a letdown! The sound quality was lousy. It sounded like somebody put a mike in the back of an auditorium and taped a lecture. Life is too short for bad microphone placement.
I searched for other podcasts and found a series on disaster preparedness by the Texas Historical Commission's Museum Services' folks. The first podcast was audio only. It described the purpose of the series. The remaining podcasts were video podcasts with a conservator from Amigos Library Services demonstrating how to respond to water-damaged books, papers, textiles and objects. The sound quality was good. The camerawork was poor in the first video but got better in subsequent broadcasts.
