From their site:
1) You can submit a video no more than 3 minutes long of a reading from a banned or challenged book. The video should include information on where and why the book was banned or challenged. You may also add a comment about why you believe the book is important. Please keep your remarks brief.
2) A video of an eyewitness account of local challenges can be submitted. This video should be no longer than three minutes long.
3) Create a promotional video for Banned Books Week like the videos featured. The video should be no longer than five minutes long. The video’s message should focus on celebrating the freedom to read during Banned Books Week.
Follow the links above to find examples of videos, and the celebrity contributions are well worth watching too. And here's the video I posted last year.
If you choose to make a video, I'd love it if you came back and left me a link in the comments!
