Number one comment by far of this blog...I am sometimes/usually/never able to watch the webinars live.
My response. Remember that many webinar providers are generous and will allow access to the recorded event...but you must register.
As an example, see this note from the provider of the School Library Journal webinar below:
"If you are not able to make the live webcast of Nonfiction Book Buzz, register now and you will get an email reminder from School Library Journal when the webcast is archived and available for on-demand viewing at your convenience."
