Yesterday, a group of us attended the virtual conference Handheld Librarian.It was presented as a combination of PowerPoint presentations with live voice-overs.Attendees had to log into the conference site to watch and listen; attendees could submit questions and comments to the presenters and moderators in real time via IM.The topic of the conference was delivering library services via mobile or handheld devices.

The conference was so well attended that we were unable to log into the opening keynote session for about 30 minutes until they opened a second log-in site.Four hundred seventy-seven individuals or groups attended the morning sessions.
