Jennifer Bednorz’s has created several Glogs* of Book Trailers - see below.
( *Glogster provides an online poster creator, which enables video and audio to be added to the poster. There is a gallery of graphics available, but users can upload their own images and media. Users can record video and audio directly at the site.)
Jennifer's glogs are grouped by book list or genre. Could be an interesting way to present book trailers in your library. Create a glog that has trailers for books available in your library. The kids could click the trailers they want to watch on the computer from the interactive poster.
