Great elementary library blog. This particular entry has several videos for back to school. There must be an elemchat on Monday-- maybe the first Monday of the month?
A nice blog post from the 2018 Australian campaign for school libraries. Near the bottom, you will see a link to a page that includes a webinar that was very good, although there were technical difficulties.They had hoped to edit those out for the finished recording.
John Schumaker's (Mr. Schu) blog. Recently featured on the cover of SLJ, he's a Chicago area librarian. This page shows the top 10 books in his library this year, complete with author/book videos for each title. Great idea for reading promotion.
