Some interesting things to share:

Steven reports on Westerville Public Library's new castr service, billed as a "podcast delivery system." The current content consists of three videos, all available via the handy podcast feed.

ResourceShelf reports that AOL has finally launched their AOL Search Podcast Beta, using the same technology that powers Podscope.

iTunes has changed their podcast categories, so if you have submitted a podcast to their directory, you may want to look into this. Jason Van Orden tells more about the changes.

Thanks to a screenshot courtesy of Michael Stephens, I see that LISRadio is now available via RSS. At long last!

And don't forget to check out the California Library Association's too cute Summer Reading Pawedcasts (with according feed).
