I've had these two items sitting in my browser for a few days, so I can't remember exactly how I stumbled across them in the first place (most links of this nature are coming through a del.icio.us podcasting feed).

Robyn Rosenberg has a blog dedicated to Podcasting in Libraries and Higher Education. There's no RSS feed shown on the site, but I managed to dig up a feed through elementary guesswork.

Brian Ferguson, author of A Librarian's Journal, has done some experimenting with podcasting. His efforts are archived at BrainWave. Here's a podcast feed.
