If you’d like a short video to introduce staff or administrators to the concept of virtual reference, check out this YouTube video from the Arlington Heights Memorial Library.
This approximately five minute video discusses why a library might want to have a virtual service and has a short demo of IM reference.
This seems to be a video by librarians for librarians, but worth watching for anyone not involved in IM reference who doesn’t have a lot of time to research the issues.
Arlington Heights has posted a number of other videos on YouTube, some of which do seem to be more patron oriented.
weekly
Everything is fairly recent, looks like they’re going for weekly broadcasts. Ambitious but a nice short format though so its doable. The virtual reference piece looks like it was done through What’s New At Your Library though, everything else in-house.
