I subscribed to The Web 2.0 Show for this task. Each episode is a conversation between two non-nerds and someone who has developed a new Web 2.0 tool. The one I listened to was with Chris Matthieu, the developer of Numly. Numly is an attempt to develop a copywrite system that can be used in a web 2 environment. A Numly Number is an ESN or Electronic Serial Number for digital stuff - podcasts, bloggs,etc. It is a unique identifier that allows an author or publisher to assign to content and track licensing of each id assignment.
Pretty heady stuff, but something that as Middlesex County Library's designated tracker of all things copywrite, something that was of interest to me.
The Web 2.0 Show is a worth while podcast.
Of more direct application to libraries are the Sirsi Dynix podcasts. The podcasts are seminars on a variety of topics.
